We're well aware of how to run a test, and a lot more than 900 keys were sent out to gamesas alone

I cannot provide full details on the test but in a general sense the scale is quite 'small' as I have mentioned before.
To answer the original question, no, no more keys are being sent out for the technical test of Crysis 2 MP on Xbox 360.
I dont understand it though, I was invited, but havent received a key? Whats up with that?
Not everybody that signed up through the invitation email recieved a key, in fact, only a minority recieved anything.
That goes and figures, I guess. So random.
