Last year they had the popular config with i7, GTX 680m, 1TB fusion drive, and 8GB Ram so I would assume they would do the same this year, but don't count my word for it.
The store-stocked high end model is now outfitted with a 3TB Fusion Drive. I don't remember the graphics card model but it's 2GB VRAM. I think it's $2799 if memory serves but I'll have to look at the smart sign again next time I'm there.
The store by me still doesn't have the "best" model yet - just "good" and "better".
