Yes I did mean 7950 & 7970 will be new (low cards will use same architecture). 7990 will likely be two downclocked 7970s is history is any guide.
28nm is half of 40nm. Remember it is two dimensional.
So (28/40) * (28/40) = 49%
Another way to look at it is, a chip with same number of transistors would have a length 70% as long and a width 70% as long thus the surface area would be 49% as much.

Ah, of cause. Obvious when pointed out
