Those lines with the pawn pushes and sacs after 6...c5 are well known and dangerous at least since the 1960ies when Gunderam invented his gambit e4-e5 (after 7.d5 e6 8.Be2 exd5 9.e5) which is now in the off due to 9...Ne4. 
But what has White against Palliser's rediscovery 6...e5 ("The 4PA doesn't prevent 6...e5" in Dangerous Weapons - The King's Indian)?

Have you had a chance to look at Watson's game against Minasian where as white he faced 12.e6 fxe6 13.d6 Rf8 (given under the link above http://www.chess.co.uk/twic/jwat94.html)?

And as previously mentioned there is the move order even recently used by Radjabov: 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4 0-0 6.Nf3 c5 7.d5 e6 8.Be2 exd5 9.cxd5 Nbd7. After avoiding the direct e5 lines with 10.0-0 Re8, then e.g. Watson has then suggested 11.Qc2 (Jobava played 11.Nd2 versus Radjabov) 11...Qe7 for black (or 11...a6 12.a4 Qe7) 12.Re1! (Watson's annotation - 12.Nd2 Nb6 13.a4 Nfxd5; 12.Nb5 Nxd5!) 12...Nb6 13.a4 Bg4 getting the bishop out to g4 (if necessary it can now exchange itself and then the knight could go back to d7 if forced with black having resolved the issue that some of his pieces are stepping over each other and all want to occupy d7). If white prevents 13...Bg4 with 13.h3, then wants seems to think that 13...Bd7 is fine.

Radjabov played this line this year and Banikas deviated from Watson's analysis with 13.Bd2. Perhaps 20.axb6 improves white's play so that he is equal, but black has various other ideas before (perhaps e.g. just 18...a5 or 18...Bd4 so that the white queen cannot go back to f2 in some lines?).

Yeah, but I don't really trust Semko's 12.e6 suggestion.  I prefer 12.Bg5 or 12.O-O.

If the 4 pawns attack is good,
why isn't it played at top level?

I don't think it's good to have such a big center, it's too big, in a way you also lose tempo moving 4 pawns instead of pieces so early in the opening, also you restrict white possibilitys of building up a position, because the pawns can't move back.

e4 e5 bc4 is not as good as e4 e5 Nf3,
because it is better for white to decide later on if it moves to c4, b5 or e2.

Same in the 4 pawns attack, white should make use of the center, but not too much,
white can later decide when to do certain pawn moves (pawns that can't move back).

I second TN's post and will ask another off-topic question.

I recently took up the Kings Indian and I looked at one game Nogueiras-Kasparov 1989 which goes:

5.f4 0-0 6.Nf3 c5 7.d5 e6 8.Be2 exd 9.cxd Bg4 10.0-0 Nbd7 11.h3 Bxf3 12.Bxf3 Re8 13.Re1 Rc8 14.Be3 b4.

I am curious if this variation still holds up for white. Is 13.Rc8 still the mainline and is 14.Be3 the move? In the few online games I have played white follows this variation and then goes 15.a3 whereupon all I know is both players are trying to create a passed pawn.

In Kasimdzhanov's chessbase DVD he says that he hasn't studied much theory at all and he argues that it is in fact not necessary to do so. At the moment all I am doing is looking at games. In your opinion is this a sufficient?

Ah, Vierbauernangriff.

It's a yeomanlike outline of variations.  I suppose I like it a little better than Konikowski's work.  You need chess German, of course.
