I wouldn't say it could be overhyped if we're only hearing about it now...
I hope it's good news about the Wii, obviously. If it's bad news, that would suck, but hopefully that's as unlikely as I think. If it's bad news for the PS3, it's par for the course or whatever, if it's good news, it's still unlikely to turn the tide. I don't really care about the Xbox 360 so I doubt I'll care no matter what, especially if it's another new wireless accessory or a new but generic game or something like that.
Then again maybe I'm doubting it all. If it's MAJOR, then I SHOULD care, whatever it is for whichever console it is, but then I'm hyping it up, now aren't I?
All I THINK I care about is the Wii launch date and price, but if they announce even one of the two, aren't they killing the point of their event next week?
EDIT: If it's Eastern Time, and I live in Mountain Time, does that mean I might catch it very shortly after 10:00 PM? I could always stay up late - but not much later than that unless I'm sure it really IS MAJOR...in which case I might not be able to sleep. >_<
