I'm actually thinking of buying a PS3 and rebuying the game (the Gold Edition of course) and purchasing that free Move upgrade.
Why? Because RE4 on the Wii is literally flawless in control. The aiming is super easy.
Why? Because the controls of the Move are almost exactly like the Wii from the looks of it.
Why? Because instead of using a very thin and unreliable red laser, I would be using a easily see able circle reticule. (Actually, I wouldn't mind just having that without the Move controls.)
RE4 on the Wii is so much fun and so addicting that I wantt o feel that way with RE5 as well. Plus, the PS3 is a much more reliable and less expensive console.
Anyone else plan on doing this?
