Reason I bought a 360. I hope Resident Evil 5 is worth it. To be honest, I love Resident Evil 4 with every gaming part of me, and the fifth better feature the same awesomeness the fourth one did.
I just realised the majority of the sound effects in there are recycled straight from RE4.
This trailer is old, and I'd imagine these sound effects are just simple placeholders. Most games features placeholders, even when trailers and in-game footage are released. Twilight Princess, for example, featured Link's voice from OoT for a while.
