I don't want this to change into another mouse debate though.

Herein lies the problem:
Bluetooth mice are fairly expensive.
Up to now, despite the fact that Apple's mice are sold at horrendously high price points (I mean, they aren't
that great!), a replacement with better features is very cheap (even as low as $10 if you want really cheap).
But, Bluetooth mice are expensive. Makes just "discarding" the shipped Apple mouse much harder (and yet, still necessary ... development work with a single-button mouse is next to impossible).
Personally, if Apple continues with the single-button mouse I for one would much rather they just keep the old model and not waste money on developing and shipping a new model. Yeah, it adds only about $20 to Apple's per-machine cost, but I'd rather save that for a third-party implementation with enough buttons to do my work and a nice wireless setup. I just hate to see this effort wasted, and for the vast majority of "switchers" (be that from Windows or Unix), any one-button mouse implementation is just plain wasted effort.
Now, as for the wireless keyboard ... I don't see the advantage there (a mouse cord gets in the way at times ... my keyboard just sits there on the desk regardless of what I'm doing, it's cord never moving ...) and see many problems (keeping battery charge, security, hijacking possibilities, etc).
Maybe Apple will come out with something to blow my socks off, but the basic idea of shipping a BT keyboard/mouse combo frightens me.
