I'm sure there's plenty of time to optimise and work out most of the bugs between now and when it's released. I'm pretty sure at this point it'd still be in alpha.
In other news the details for the collector's edition
have been released. Looks like they're stealing ideas from the Dragon Age team as there's going to be a robo-mabari companion. I think it's just for the Normandy though, not an in-game combat thing. I do wonder about the extra character & mission bit though. Probably similar to Zaeed in ME2 so probably not worth getting excited about. One assumes everything DLC-wise save perhaps the N7 weapons will be in a not so fancy digital deluxe download package like with ME2, though they probably won't say so until they've secured a fair number of hardcore gamer pre-orders.
I heard the N7 weapons are in the Digital Deluxe pack. The DLC mission and the physical stuff aren't included.
