Is this good news, or bad?
What do you think, will Apple release a fix for our problem after that calls?
I don't remember seeing such a file in my EFI partition before I flashed (I did look) - but if you've got one, I think it's worth a try
lol, i didn't thought about it.
In a real, i dont know where to get this file.
I thought somebody can extract firmware from stock rMBP, but i dont know - can it be done, or not?
I do not know, but I think they prioritise things based on the number of affected users, or so should they do :-D
Good news for us ... I've talked to an Apple employee these days, and he said that Apple knows this problem and is working on fixing this with the next EFI Upgrade for Retina MacBooks. So stay tuned ... Apple software engineers are working on it. 
Maybe the problem is fixed within the next few weeks ...
Maybe the problem is fixed within the next few weeks ...2 months have passed , they are fastter then light...
I did not expected this from Apple...
No ETA, 2 months passed - no fix. Oh god. Bless Steve.
If anyone wants here is the EFI boot file in my macbook pro retina:
http://box.houkouonchi.jp/Firmware.scap
It was in this folder on the EFI partition:
/EFI/APPLE/EXTENSIONS
I primarily run linux so I have not done any of the apple updates nor have i seen/noticed an issue like everyone talks about in the thread.

It is exactly the same that I have on my MacBook Pro Retina with EFI updated. What about the content of /EFI/APPLE/FIRMWARE ?
I don't have that firmware folder at all:

-rwxrwxrwx 1 german staff 8454768 Sep 20 02:15 MBP101_00EE_B02_LOCKED.scapthat's the content of my EFI partition, so it seems that the new EFI is the MBP101_00EE_B02_LOCKED.scap
maybe just that file is loaded during boot up "fixing" what apple thinks need to be fixed. I should check if there is any info on Mac EFI boot up procedure. And what happens if I remove that file.
Edit: I downloaded the EFI update package and check the content and the scripts, it use the bless command to mount the new firmware (the .scap file) so maybe the copy under /EFI is only for installation, but we cannot got the old one back. So we need to wait for Apple fixing it.

I accidentally left my rMBP on when I slid it into my bag the other day...
And as you can guess, the fan went full blast. The computer was piping hot inside. By the time I reached for the bag, it was 5 hours later. The CPU was reporting 110C.
So I left it alone for the fan to go full blast for 30 minutes, and then I started checking for various things.
No problem. EFI bug didn't occur. So obviously it wasn't triggered by temperature... Either that or I somehow got rid of it for good.

Maybe fixed
Been testing 10.8.3 for a couple of hours and performance seems to be a lot better.
Will be testing it more later today.
Borderlands 2 is playable at 1920x1200 settings on medium/high. (OSX)
Before it struggled with 1440x900 at low settings when it got hotter.
EDIT: it's not fixed in 10.8.3
Once the gpu get's up to temperature, performance drops again.

Couldn't hurt to try it.
Anyway, stay away from the beta. It freezes the computer every now and then.
