Well, looks like we asked for pics of the 48xx's and we shall receieve (need translator!):

Some tidbits:
-Second generation 55nm process
-TeraScale engine (?)
-GPU can do physics, ray tracing, AI, stream computing
-2 x 6-pin PCIE connectors for the 4870SKU

Too bad no other specs but the cards themselves look good!
