In an interview with GameRush.nl Masachika Kawata (Resident Evil 5) told he thinks it's logic Japanse developers have difficulty developing for the next generation consoles. Developing for the next generation is easier for people who are used to developing for PC.
Kawata thinks his team and everybody at Capcom is doing a great job in the production of Resident Evil 5. And of course they feel pressured. Not only there's the huge success of Resident Evil 4, but also just by making a Resident Evil game people get high expectations.
Kawata wasn't very clear on the possibilty for a PC version of his game; "When the fans want it, we will consider developing it."
