There's only one gtx 770 4gb for sale that I see. Is this a mistake or why are other brands not selling this card with 4gb?

Right but only Gigabyte is providing the 4gb version, none of the other brands are... why is that? It has actually been for sale for a week.

A week is NOT a long time, especially for releases. The reason why is because 4gb models target smaller niches than standard models. If manufacturers can crank out cards that have the probability of selling more they would, having release bulk of 4gb models and having them hang on shelves don't provide profit.

eVGA will have their GTX 770 Classified's out next week. Which is obviously gonna have the ACX style or GTX 680 Classified blower style coolers with 4GB of VRAM.

so, does this mean 5GB 780? It'd look bad if the 770 had more VRAM than the 780

No.

The GTX 780 has 384 bit bus, not 320 bit bus

For the GTX 780, 6GB would have been the natural "step up" due to its 384-bit memory bus consisting of 6x 64-bit controllers. Only 3GB or 6GB configurations would make sense technically for such a 384-bit card.

However, AIB partners have stated that NVIDIA will not allow a 6GB GTX 780 due to the possibility of such a card cannibalizing the Titan's sales.

Were such a card made available (for perhaps $749-$799), the only advantages that the $999 Titan would have over a 6GB 780 would be 2 extra SMX clusters (14 vs. 12) and better FP64 performance (1/3 FP32 vs. 1/24 FP32), which is useless for gaming anyhow.
