Wii’s hype gives Corruption some potential from a sales perspective, something that the previous two Metroid Prime games have lacked. That said, the window of opportunity is short. Hardcore fans read reviews, and if the reviews are less than stellar, Corruption will have failed to become the must-have title it needs to be, and by the time Halo 3 comes out the next month Samus will be all but forgotten. But if Retro can deliver a great single player component (which it has proven it can do) and serves up an adequate online multiplayer component (which it has not yet proven it can do), Metroid Prime 3 could be something special indeed. If either of those components are absent, however, it will be hard to shake the notion that Corruption was a lost opportunity, especially for a title that was supposed to release months ago.
Regardless, August 20 promises to be an important day in the life of Nintendo’s new console. Whether Corruption will be the definitive hardcore shooter for Wii remains a mystery, at least for now.

From the few previews out there, Retro has got the controls down pack, so I think they will deliver on that. The whole reason MP3 was delayed from being a launch title is because Nintendo and Retro want it to be perfect. MP2 was a disappointment for them and to the fans. They want MP3 to met everyone expectations and it probably will. MP3 is also the last Prime game so of course they want it to make it the best. And it's not known yet whether Corruption will even have an online mode. But even without that I think the game will turn out great.
i just cant wait to play a great FPS with the wimote, it should be amazing
Never mistake Metroid Prime for a FPA Its FPA
And did you never own RedSteel? Call Of Duty? Medal Of Honour? Farcry?...o about FarCry Lol,lets forget i mentioned that

Reggie himself said the MP# controls will make the FPA feel like a FPS.

I said good FPS-call of duty was clunky, IMO
i really hope it has Multiplayer that would be good
According to the info Rooster found it doesn't have any offline multiplayer. But it's still unclear if there will online multiplayer.
i dont need multiplayer for a great game experience
I still say that nothing is writen in stone untill the release date...
Nintendo could pull a huge press comfrence 2 weeks before launch and spill the beans oh all the online goodys and what not!
Just wait for an offical word from nintendo or web sites that start getting it earlier on....
Heck, they may already now that there is online but they could be under a hudge imbargo!
Just wait...
We will hear sooner or latter about everything! lol
August 20? Is that the official release date of MP3?
Yes, it is.
There hasn't been one good FPS on the Wii yet, which is why its smart for Metroid to continue its FPA genre. It may control like an FPS, but its still an FPA game. Because you aren't clearing levels, saving then moving on to the next. Metroid games are known for the exploration, not just simply blowing through levels.
Metroid Prime 3 will be FTW no matter what the idiotic reviewers could potentially say about it.

Indeed it is, you actually didn't know that

Exactly.
I know it will be bada$$!

This is a positive to this game not being as uber hyped as Smash. It doesn't have to worry about the pressures of being supreme and less pressure and expectations = good.
Too much pressure and expectations = Twilight Princess

Completely agree

Twilight Princess made those expectations! Plus Metroid Prime 3 is already the most hyped game in my book. Because I believe that Brawl will kick @$$ no matter what happens. metroid is a proving ground for the Wii and that is definitely hype.
I don't think its possible to be as hyped as Smash is anyway...
I don't see why you didn't think TP stood up to its expectations...
It was absolutely fabulous in my books!
I agree with LMX about Twilight Princess not living up to expectations and as for Prime 3, if it's half as good as the first two it'll be awesome, but it has the potential to be better, so I don't think we've got anything to worry about, we're in safe hands with retro.
