From my understanding after having read through other groupbuys & posts on this forum:
the U2+ is pre overclocked at 2Ghs by default, hardware is identical to the U2. I assume older batches (such as the ones for this preorder) are the original U2 and newer orders come "updated" as U2+.
It's a bit confusing when Bitmain themselves label them as U2+ on their website

Only thing changed is the heatsink, they finally ran out of the "better" original asicminer .333 blockerupter H/S that they made billions of.
Antminer just reprinted them.

The original design was better in one respect, smaller more room in hubs to stack em, they did not overheat.

I believe the U2 is simply WoW factor but foolish.

I never saw anything concrete on that. Are they actually too close to stack in a USB hub or not?

my guess is that it depends on the hub and from the pics im going to say if not touching they will be very close to one another but all that is just a guess some hubs are at a slant i would guess you could fit more on them?
