That´s right but he transposes into the line you have mentioned already after 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Qxd4 Nf6 5.Nc3 Nc6 6.Qa4. He claims a small edge for White here (which he does in every line he recommends).

That is true, my mistake. I haven't studied the book yet, just had a brief look mainly to see what is recommended against the variations I play as Black.

I think this is also what Korneev recommends in Rossolimo and friends.

no catch - 3.d4 is not a worry, nor should 3.h4!?! be

I thought SOS 6 dealt with 1.e4 c5 2.Nf3 [Instead of 2.Nc6] g6 3.h4!?.

I agree with you though that this line can't be trusted, as Black need only play the natural 3...h5 and White already has to be very careful how he proceeds.

What about 1.e4 c5 2.Nc3 g6 3.f4 Bg7 4.Nf3 e6 ? What's White going to do with Bf1 ?

I play this line with Black. I don't see a catch.

Black avoids 2.Nc3 Nc6 3.Bb5, which might not be very scary though.
Black also keeps the option Nbd7.
The alternative 2.Nc3 d6 3.Nf3 is also problematic (or 3.Bb5+ but here White does not have c3 or c4). 3...g6? 4.d4 is very good for White, and 3...Nc6 allows 4.Bb5, but again White has committed to Nc3.
Another option is 4.d4 cxd4 5.Nxd4 g6 which is not quite a Dragon yet (6.Nxc6!?).
So Black has to play 3...Nf6, but here White can tease us with 4.e5!? or a King's Indian Attack with 4.g3 where some players prefer the knight on e7 rather than f6. But at least Black avoids the Big clamp (c3).

After 2...g6 3.d4 cxd4 4.Qxd4 the position has some nuances compared to the same line with the knight on f3.
4...Nf6 and now:
a) 5.Nf3 transposes to the other line where 5.Nc3 is a commonly played move.
b) 5.Bb5 a6! is also ok for Black here. The idea is the same as with Nf3. 6.e5 axb5 7.exf6 Nc6 (In the 2.Nf3 g6 line Black can also play 7...e6 here. Since White now has 8.Nxb5 it looks bad, but after 8...Qa5+ Black is probably ok) 8.Qh4 and here Black is deprived the 
ressource Ra8-a4. Still 8...b4 wins a tempo (normally it blocks White's queenside) 9.Nd5 e6 and Black is ok.

Also interesting is 3.h4!? Black should probably reply 3..h5. White does not have a Smith-Morra gambit in hand and should be happy in a regular Dragon.
Either Black reaches the Soltis variation or delays castling if White plays 0-0-0. Then White would probably have preferred to play g4 before h4.

That's not true. It's not an improved version of the Hyper Acc, just a different one.
1.e4 c5 2.Nc3 g6 3.d4 cd4: 4.Qd4: Nf6 5.Bb5 a6 6.e5 ab5: 7.ef6: e6 (Nc6!?) which is unclear.

After 5.e5 Nc6 the drawback is that the pawn e5 is unprotected so white has to play 6.Qf4 Nh5! 7.Qe3 d5! or 7.Qe4 d6 (f5!?) also with unclear positions.

So I think for an Hyper Acc dragon player 2. ... g6 doesn't have drawbacks, one benefit is that it avoids 2. ... Nc6 3.Bb5!?
