How much longer will analog sticks be relevent in gaming?

[Grey Acumen]

Actually, as technology improves, it may be possible to provide tactile feedback to touchpads, at which point analog sticks will become unnecessary. My only issue with touchpads is the one already brought up, you need to look down to be able to see what you're pressing or exactly how things are centered.

It would be rather interesting if this every could get implemented, as it would allow for control layouts to be fully tailored for the game, rather than the game having to be tailored to the console.
