The hi-res textures are nice, but it'll be a problem if it still has the tinny enemy sounds as a holdover from the PS2 edition, like the PS3 HD edition does.
This is actually the thing that annoyed me the most about the PS3 version and why I still haven't finished that port to this day. The sound mix and quality was HORRIBLE. I can live with a few missing effects but the samples were terribly compressed and the positional mixing was all over the place. I hear the 360 version was better though.
Even if this version was otherwise perfect, bad mixing means I'll just go back to the Wii ver again, 60fps be damned.
