Honestly, I know the PS360 is more the "gritty realistic market", but it's for that reason that I wouldn't be surprised if RE5 could get lost in the shuffle of the sheer number of games we have in the same/similar genres.
It's happened in the past that games like this have gone mostly unnoticed when the market is flooded with similar titles (like some of the party games on the Wii).
That aside, it makes little to no sense to build up attention to the RE franchise on the Wii and then move the franchise to another console.
Frankly, I've never understood why companies will do this, like how Konami releases Castlevania games on the DS AND the PSP, so if you're a Castlevania fan, you have to buy both if you want to play all the games. Logic dictates that you should just have to buy one console to get all the games from a certain franchise, otherwise you're basically forcing your fans to buy additional consoles that they don't necessarily want.
"I mean, c'mon, Viva Pinata, a game with massive marketing, didn't sell worth a damn to the "sophisticated" 360 audience, despite near-universal praise--is that a sign that 360 owners are a bunch of casual ignoramuses that can't get their heads around a 'gardening' sim? Of course not. So let's please stop trying to micro-analyze one game out of hundreds and using it as the poster child for why good, non-1st party, games can't sell on Wii. (Everyone frequenting this site knows this is nonsense, and yet some of you just can't let it go because it's the only scab you have left to pick at after all your other "Wii will phail1!!1" straw men arguments have been put to the torch.)" - exindguy on Boom Blocks
