So yeah, what are people betting here? historically speaking Nvidia's approach to letting re-branded cards SLi with the older brethren has been inconsistent however the last time they did it (8800GT to 9800GT & 9800GTX+ to GTS250) they were okay with it, but of course much water has passed under the bridge since then.

Geforce 600/700 SLi compatibility?

A simple bios flash to get the older card recognized as a newer one should make them SLI-able

you first 
until they are released we don't actually know what the differences are between the two, anything at this point is pure speculation

Even if you could, I would not bother. If I had a GTX 680 already, I would just go out and buy another second hand and overclock the nuts off them.
It's a whole lot cheaper and better than the risk of bricking a brand new GTX 770.
+1, seems a bit daft to set your sights a GTX 770 to SLI with a GTX 680 when you can just get a GTX 680 and save yourself a bit of money while also knowing it will work.

Other way round matey! Flash the 680 to 770, wouldnt want to risk the 770
In fact I wouldnt want to risk the 680 either. Damn im poor. 560ti SLI ftw...

I think you may be taking quite a risk with the GTX 680. One area you can go wrong is the vram, the GTX 690 most people think is just 2 GTX 680s on the same board but there are differences. The GTX 690 uses different vram to a stock GTX 680 which almost always lets you overclock it to well over 7000mhz. I suspect that NVidia has done something like this with the new GTX 770 to get the high memory speeds. If you flash a standard GT 680 to a GTX 770, even if it takes you could still end up with a very bricked card where something like the vram lets you down.
It really wouldn't surprise me at all.
Additionally, flashing a graphics card BIOS isn't really a risk if you have more than one graphics card anyway.
It's only ever been a risk if it's a bad flash and then you can't get any display to flash the original/working BIOS back.
