So what do we have? (it would've been helpful to have some subtitles to denote the odds stated... 😛)
■StarCraft 2 - 10:1
■Resident Evil 5 - 70:1
■Fallout 3 - 5:2
■Spore - 3:2
■Left For Dead - 9:2
■The Force Unleashed - 7:1
StarCraft 2? I'm not quite willing to make a bet on it either way. I suppose that at this point, chances are solid in favor of it. I can't say I have all that much experience with Blizzard's work, though what I do know suggests that they may very likely make a fall release date. I'd probably be in favor of it, though only with moderate confidence.
Resident Evil 5... I think the case was laid out well enough for it. I wouldn't place a bet AGAINST it purely because odds would mean that my money would be better put to use on other bets. But I'll call that it won't make it. 😛
I'd place a bet in favor of Fallout 3 coming out this year, knowing Bethesda pretty well. They're well known for witholding a lot of information, lest they have to retract it. (they've had to retract SOME things in the past, but they've been loathe to do so) If they were confident enough to lay out a release date like that, I think that chances are good that content-wise, the game's pretty close to finished. Some voice-acting, swapping out some place-holders with final art, etc... And of course, further optimization (though it looks like they might not need so much here this time around) but most importantly, bug-testing. The "silence" about it? Does anyone remember Oblivion's utter lack of a gameplay trailer publicly available for the longest time? They like to not give out information. So in short, I'd confidently put a strong bet on it.
Then there's Spore. I'm actually NOT as confident in it as I am Fallout 3's release, but I'd still call at least ONE version ariving. I would not be surprised if we only do get one version this year, and have to wait for others.
As for Left for Dead... To be honest, I've not been paying all that much attention to this, even though I've been mildly familiar with it. So in this case, I'll have to pass on making a call.
Lastly comes The Force Unleashed. Major title, everyone's been waiting for it... And for quite a while. And the release date still seems to be sitting pretty close. So even if a delay's possible, it's doubtful, I think, that it'd push it into next year. So I'd place money on this one as well.
