I was waiting for those numbers as well. In another thread regarding 370x GPU performance here, a member was noting throttling when running Furmark. I also noticed that when I was running Afterburner on FireStrike, between load screens it looked like the core clock speed was only 400mhz. Could it be that the ATI driver is throttling certain apps by their file name (i.e. Furmark.exe)?
This could explain why 3DMark11 numbers suggested higher Firestrike numbers. If 3DMark11 wasn't on the drivers list of apps to throttle, but 3DMark/Firestrike was then those numbers were just throttled and the 3DMark11 numbers were legit. It makes me wish I would have benchmarked the 750m and the 370x in Windows back to back in WOW, D3, Tomb Raider, and a few others before returning the new system.
I have an auto-alert configured with BHPhoto for the fully loaded system with the 4980HQ and 1tb SSD. I am passing on the iMac for now due to folks saying the 295x runs too hot and throttles frequently. I may see if they update the Mac Pro at WWDC in 10 days before doing anything. Could mean steep deals on current systems, and also interesting possibilities for what they use in D300-D700 updates. I know that the Mac Pro in Windows can run XFire on games, which would have been interesting.
