two games i'm buying next week:
****** Legend (for my xbox360 - the reason why i'm getting it for xbox is because i found the ps3 demo wasn't as good. mainly the sound FX. it sounded like the sound fx were recorded in low quality on ps3 ...the music and voices were okay on ps3, tho. on xbox everything was perfect. i tend to prefer multiplatform titles on xbox anyway. they tend to be a bit more polished, imo. developers tend to just port the xbox version over to ps3, which leads to ps3 versions sometimes not being as good)
Uncharted 2 (for my ps3)
those two should easily hold me over until COD: Modern Warfare 2 comes out in November.
