https://sfminer.com/index.php?action=page&uniqueid=aboutThis product just hit Sina Weibo (though it is not currently trending on Baidu or Weibo). They have announced that their ASIC mining systems for Scrypt will be turned on around June 1, 2014. They estimate that their product is faster than GPU mining in terms of hash / power consumption (~300 kh/s at 5W versus 160W for a Radeon 7850).
They are accepting pre-sales for shares into this company (similar to ASICMiner business model). For 0.5 BTC you can buy 1 share of stock (until January 20th when it goes up to 0.7 BTC).
Very little is known about the company, no owner, there are no personal names or business addresses attached to it. If you create an account and log into the system the share availability fluctuates widely but it is not clear why (went from 690 to 802 in about 10 minutes). Will add more details if I learn anything new.
Until they show a video of the actual chips with screenshots of the hashing results, do your due diligence. Here's an article about similar credibility and claims issues with the Alpha Tech Scrypt ASIC:

All of this is located in Beijing. Here is his Weibo profile:
