Let's not extrapolate too fucking much here ok. No-one is talking about switching billions of keyboards worldwide.
They're designing a keyboard here, and wanking for months over tiny things like 0.2mm worth of champfer (whatever that is) in order to make typing on it more comfortable. Since the k/b is mostly being sold separately, they could pretty easily offer a different layout as a separate option. If it catches on, whoo hoo, they have another patent to whore out. While they're at it, they could tidy up all sorts of cruft, like the Caps Lock key, the Insert key etc too. Every time Apple cuts out some useless old piece of shit from computing's past like the floppy drive or the CD drive, everyone howls and then adopts it as standard a year or two later. Make something better and it'll likely catch on.
