About g4 with Nxe6, modern engines like Houdini does not see any advantage for white in lines like 11 0-0-0 Ne5 12 Be2 Qc8. 11 Bc4 instead Qc8 is strong as well.
However, in most recent GM games black has played lines with Queen at d7 an a rook at c8, unclear why Qc8 is not more popular.

The lines played vs Dragon has always varied beetween trends. Right now 9 g4 is trendy and I tend to meet this line more often at internet since it is a very practial line that limits blacks option while still giving good attacking chanses. 

Speeking of trends, these days I meet 9 0-0-0 d5 10 Kb1 more than 12 Bd4 line.

9 Bc4 yugoslav is still a popular as ever, only difference is that I get the chanse to play chinese dragon more often than usual but these day I usually go for Topalov system anyway.

What are your Dragon predictions for 2011? 

My hunch is that, in view of the continued expansion of the theory, in over-the-board play we shall see more Whites using move orders that reduce Black's options and channel the game into lines which might be satisfactory for Black according to current theory,  but where deep preparation has a chance of catching Black out, e.g. the move order 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 0-0 9.Bc4 Bd7 10.h4, when 10...h5 is supposed to be the best. But being forced to fight in the labyrinth of the Soltis is maybe not really to the taste of players who want to play the Chinese or the Topalov.
