New consoles have usb ports which can make such things possible, Keyboards in PS3's etc. The concept of a serious flight sim with off the shelf HOTAS
capability is not far away. However, as I said above, processing power and graphic capability always lets them down. Until a console comes out that can seriously go up against a high PC then I'll always be looking at a PC for my gaming/siming.
You only have to look at the Car sim market to see that consoles have made an impact there.
