Even though Resident Evil 5 producer Juntake Uchi thinks the Wii is a "wonderful piece of hardware," he also believes that "even the title screen of this [Resident Evil 5] couldn't have been done on PS2 or Wii."
In some ways, this is an insult to the hardware of the Wii, but it's not exactly a hidden secret that Nintendo's system is vastly underpowered when compared to the 360 and PS3.
To quote: Kawata: First of all, and quite obviously, the graphics. Even the title screen of this couldn't have been done on PS2 or Wii. Online co-op as well; the number of enemies you can have on-screen at one time; destructible scenery, physics - we're using Havok this time.
We can do more complex stuff with AI; the concern I had in the very beginning is that sometimes an AI partner can become very frustrating. Now she handles fine and you can play through the game without her becoming a frustration.
When you see the new stuff you'll say "Oh my God, I can do this and this and this", but you'll probably get used to it quite quickly and then get into the story.
How complicated could the title screen of the game be that it would be impossible to duplicate on the Wii and PS2? More PlayStation 3 News...
