Btw, I have also a PS3 and a Wii, loading times are really too long compared to my PC with Steam on a dedicated SSD.
The worst was when I bought MGS4. When I popped the disk in, I had to wait something like two hours between PS3 update and game update. This was soooo boring. I remember the Wii's loading time in MH3 being quite long. I remember the jump between cartridge and disc during PS1 time that really put me off console gaming ^^
