White seems to do quite poorly with Ne5, so Nbd2 seems to be the way to go as pointed out.

There is some analysis available on youtube:

It seems the exchange sac idea is tenable. Sasikiran played 9.Nbd2 instead and got a good game:

At this year's euro-Ch Salgado tried the amazing line

1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.g3 Be7 5.Bg2 0-0 6.0-0 dxc4 7.Qc2 b5!? 8.a4 b4 9.Ne5 Qxd4 10.Bxa8 Qxe5

where Black sacrifices the exchange for interesting compensation. Note that this line is not covered at all by Avrukh and 9...Qxd4 appears to be a novelty (correct me if I'm wrong). It was subsequently used by Gustafsson, Gajewski and Shabalov, and it was speculated that Kramnik went for 7.Qa4 in his candidates match against Radjabov because he was afraid of 7...b5. However, I have not seen any games in that line since, and players started playing 7.Qc2 a6 again. Can anybody provide further information in this line, has it been covered somewhere or has Black lost some games with it?

Sample games:
