Sorry, my first post. Been stalking US for awhile. Anyway, Razer did leak the release date from what I have heard (I did not see the rumored leak) said that the gaming gear they are making is to be released a week or so before the release of SWTOR in November. Like you said, we do not know if that is to be true, but with what they are saying about Q3 or Q4, it fits. Either way, I'll have my rig by the end of July.
From what I see The game will come out in the late August to mid November time frame. Here is why
1) Bioware has said they want a short window from announcement of release date to release, roughly a month gap.
2) They have been putting out lots of info and the game is pretty much done. they have said they are in the final polish stage. They are doing testing and at the end of June there will be a large scale ramp up in their closed testing. (from bioware ceo) They have said there will almost certainly be no open beta. They have over one million people signed up for beta and they think that is a high enough number to bug and stress test the servers.
3) Comicon: My pick for when the release date will be announced. It is toward the end of July. Based on the short time they want from announcement to release that puts the game in late august early September.
4) If they do not announce at comicon then chances are very high for a November release. It wont go past that or they will be stepping on the toes of their other game releases.
My official guess, September 2nd.
Also the razor leaked date is based on the quarter estimates, not actual knowledge of the release date.
