alright -
call me keen, but i've read all of your responses, and on the surface i am seeing one main issue - some favour the snes/ps2 layout and idea (stress the idea) and others like the present gc design and ideas.
would it be totally unrealistic to manufacture two default controllers? of-course from a financial point of view this may be quite expensive, but it certainly would give gamers more options, more control over how they play games. add to that the great idea of making button configuration/assigning manditory for all games, this would put the console ahead of the game. an alternative perhaps would be to manufacture one default controller but commission a third-party hardware developer to design the other and release them at the same time.
though now a committed console gamer, i can't forget my roots back in pc land - i'm used to using almost all of my fingers for gameplay. i enjoy ts2 and other fps a lot on consoles, but the controller in place of a keyboard and especially mouse changes the gameplay hugely - enemies ai tends to be a little on the slower side (only a little, but noticeable) to compensate for the fact that you can only swing your weapon around as fast as the analogue stick permits. with a mouse, there are no excuses.
that being said, should the next controller have a totally different attitude towards control and start giving us back the use of our other fingers? playing with index fingers and thumbs is fun, but there could be something more - though this of-course could be something that sets consoles apart from pcs (don't worry, there's no turning back)
arg - seeing both sides too much...
