SerDes lanes count has been upped to 20 (up from 18 on P5020/P5010) with 2 of them reserved for SATA, but only 3 PCIe controllers (down from 4 on the P5020/P5010) with one of them fixed at x8 speed.
Sampling starting in June 2012, volume production in Q1 2013.

Edit: Price estimation:

"The company has not announced pricing; we estimate $200 to $300 for chips clocked at 1.6GHz to 2.4GHz."
