just received mail from Bitmain 

We are proud and happy to announce that we are launching the all-new Antminer X3, a new Antminer model for mining cryptocurrencies based on the hashing algorithm CryptoNight.

The Antminer X3 delivers a minmum hashrate of 220KH/s while consuming 550W of total power.

To prevent hoarding by certain users or resellers and to ensure that more individual miners in different time zones around the world are able to order this new ASIC miner, we have made some changes:

There is a limit of one miner per user for all orders in the current (two) batches.
We will release both these batches with an equal stock thrice today: at 3PM, 6pm and 9PM (15 March, GMT+8). >

after a week mining my xmcc coins are still unpaid. Dev team is not responding so i will migrate to zPool.
