Are you only selling the chips?  Or do you intend to sell a full mining system.

there is conference on 8th dec in Beijing for launch where you can pick up raw chips & development board. other regions will be added later

for now there is no vacancy for official agents/resellers outside china, so only need to check back on the website for latest news.

chips will be released over time, and slowly gen2 will be on market, with greater hashpower, but to avoid the 51% attack on litecoin network, release is staggered.

Q: How many of your mining machine chip, count how much force?
A: Same as above, we will gradually release information.

A: We provide parameters according to their own estimates.

Q: I am a United States, Europe, Taiwan ...... team, would like agents, buy .... you related products.
A: The technical information please download, we will do our best to supply the world, if you want to apply for overseas agents in other regions, please also provide detailed information, or can not get our attention. I can not guarantee that the use of multi-lingual each reply.

A: We're put in, please wait for our detailed information, in order to avoid LTC bring 51% attack, we will control system shipped. We use a multi-generation chip parallel development, and production flow sheet , and all the mining machine and chip spot sales are conducted without pre-sale, so we will choose the right time to release the right products. Our chips will not be counted in order to grab power single-chip index, regardless of the cost, stability, and supply chain speed. We design and make their own production over a number of commercial chips, which you are familiar with the product. We have 15 more years of actual products and engineering experience, from a chip to a cluster, is a systematic project, the need for effective integration from design to supply chain operations. Please wait and see our products and industry chain integration capabilities

Q: Why do not you dig?

Q: When will you be officially released and sold?
A: The next weekend we will open a small conference-related information, please visit the official website and www.cybtc.com of Gridchip area:
Gridchip GC3355 chip / mining machine Product Launch
http://www.cybtc.com/forum.php?mod=viewthread&tid=3226&fromuid=2213


While experienced a few months ago notorious Beihong times wild , with the recent upsurge currency, futures and pre-sale everywhere, chips and mining machinery industry is currently true and false news sky fly. Regardless, the mining machine is a high-risk investment, please self-assess their risk tolerance, and saw the loss of cool soaring currency, it is very dangerous.

BTW, you can focus Gridseed microblogging
http://weibo.com/gridseed
Relevant information, but also in the above publication

Gridseed

http://www.cybtc.com/thread-3246-1-1.html
google translate:
Code:
Recently it was fake Gridseed and Gridchip in online sales on behalf of the mining machine, to remind the miners:
1, Gridseed not yet authorized any company or individual selling any mining machine based GC3355 product.
2, Gridseed's official website is http://www.gridseed.com/ , in addition there is no other website.
3, after the mining machine Gridseed official product sales, will announce sales channels, price, dealer information, etc. on the official website. Not released official online sales channels all fake.
4, Gridseed mining machine products are in stock, after the customer orders 24 hours to pay the full amount, confirmed after payment is received within 3 days of delivery. Sell ​​futures were all fake.
5, for any impersonator, Gridseed right to further pursue its legal responsibility reservations. Gridseed

first sale of USB mining machine is four or five chips, depending on the final product of power consumption and heat dissipation.
Citie conducted USB mining machine price quiz, rules are as follows:
1, in this post Reply Guess price elsewhere reply invalid format roughly as follows: 4 chip USB mining machine: XXXX million 5-chip USB mining machine: XXXX yuan
2, each Only a valid ID quiz price, if multiple quiz , follow the results of the first quiz prevail. If the first quiz replies were edited, this ID is invalid
3, after the final price of the product officially announced Guess price and the final price which is closest ID, this ID to get a reward USB mining machines. If there is more than one ID, like the closeness, then who should reply who gets the mining machine
4, quiz End Time: Beijing at 8:00 on December 4, 2013 (ie within 72 hours)

So, it looks real, albeit a little difficult to plan for currently.

specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

Chips and dev boards for now

Pictures confirm the release event and functionality.  One person was able to get a single chip to hash at 84 KH/s.
