All the versions of RE5 will be compared against each other, and I think the tone will be more like "The Wii version of RE5 looks like %@#$%@# compared to the 360 version, which in turn looks worse than Halo3", rather than "The 360 version of RE5 looks worse than Halo3, but the Wii version is OK because there is no Halo3 on that platform".
As a plateform owner i mainly care about the offer that is available on my plateform.
I want to play games, i have a budget for it and i have to choose my games amongs the games that are available to me.
Why would i base my choice on what is available on another plateform ? Why would i care for what is not available to me ?
So in the end what counts is how the game compare with the other games i can buy, and, except for a few specific low-tech titles, a last-gen game on a current gen console won't be the choice of many unless there is no contender.
Maybe my analysis is wrong then we should see much PS2 ports on xbox360. It may be the case i don't know.
IMHO we tend to forget we are not representative of the masses of videogame players, they are not as passsionate/hardcore gamers as most of the forumers here.
I'm not either representative of the people here as i only own a gamecube (and a DS) and i'm satisfied with the offer of present and past titles. Not in an hurry to change the console.
Didn't make my mind yet, i wait to see things settle, price cuts, killer apps. What is currently offered by the Wii isn't appealing enough for me, the same for PS3. I wouldn't mind to skip a nintendo generation (i did skip nintendo 64) and go for xbox360 or PS3..
