I think the transition will happen, but I don't think the post above worrying that "an ARM MacBook Pro will just turn up one day, unannounced" is going to be correct. It's not impossible, but the PowerPC-to-Intel transition didn't happen that way -- they shipped developer-only machines in mid-2005 and didn't start shipping consumer Intel machines until January 2006, and took nearly all of 2006 to make that transition. I'd expect an ARM transition to be similar, and if anything, slower.
