Another logical conclusion would be that they are shipping out systems stuffed with generic parts so as not to have to waste millions of engineering dollars on developing a tiny-volume (few thousand units?) developer-only product. Since there was no decision until recently that the switch actually *would* be made, why spend massive cash on developing a whole new x86 system architecture of your own if you don't even know for sure you'll be switching, especially since you know that if you do decide to switch, the lead time you'll give to developers will provide you with plenty of time of your own to finalize the exact system specifications. I think you're dreaming if you think the x86 Mac will be a whitebox PC under the hood.
