After 2... g6, I just play 3. g3 and go into the fianchetto lines. This is fine against the KID, but I'm not so sure against the Gruenfeld.
You also have to decide what to do against 1. d4 Nf6 2. c4 e6 3. g3 c5
There was another thread where this was discussed. The choices are more or less 4 d5 or 4 Nf3, both of which are OK and neither of which are especially awesome.
Another problem is what to do if your opponent plays the Slav, 1. d4 d5 2. c4 c6, where the Catalan fianchetto isn't so strong. There's nothing wrong with the lines, but white tends to get kind of a microscopic advantage in a lot of them.
