Again, these are all just speculations/rumors (hence appropriately call MacRumors). I was just referring to the dream specs. in many of the forum user's specs. wish list (USB 3.0, Blu-ray drive <-- just to name a few), even though i don't see them necessarily happening in the upcoming refresh, but perhaps as an optional upgrade?? I don't know, but if not in this refresh then quite possibly by the end of the year?
I so highly doubt they implement USB 3.0 when they are helping with light peak, which i wouldn't expect to see on machines until next summer (2011). Wasn't the first USB 3.0 product just released, or even announced? Some external HD..
