So I finally have the funds to order a MBP and of course it's two days before an Apple event. I would think it would be safe to go ahead and order a MBP since every rumor says no new MBP until next year since we just had a refresh, they follow Intel's roadmap, and the tempo of updates is pretty steady. However, what I'm wondering is, if I ordered a MBP today, would it come with Mavericks or Yosemite? Since I'm ordering the custom built model (upping the CPU and RAM) it wouldn't ship for 1-3 days and unless there's a room in China somewhere with the Cadillac models sitting around, it'll potentially be manufactured to order. Would they literally wait until the launch before putting Yosemite on machines? Or should I wait until after the event Thursday to order? My only concern with ordering Thursday evening or whatever is that if they say "go order the iPad Air 2 now!" then the store will be swamped, to say nothing of how I don't know if the mass shipping of other products interferes with the MBP shipping at all. Of course the more I type the more I realize this is an idiotic first world problem. But anyway, does anyone know (or have a good guess) if, supposing Yosemite final is released on Thursday, how soon a Yosemite MBP would be available for order? I guess the only reason to wait for Yosemite is to save a step should I ever need to do a full recovery.
