Okay, first of all, I'm doing something wrong here, I should group my responses and think a little longer about it. This is mail, not chat. My apologies. I think RSA has seen more cryptanalysis than DSA and ElGamal, which is in favour of RSA. Also, RSA allows hashes other than SHA-1, whereas with DSA you need to switch to DSA2. So to get support for other hashes, a switch would be necessary anyway, and less applications supported DSA2 at the time I believe. A signature by a 2048-bit DSA key is twice as large as a signature by a 2048-bit RSA key, but offers the same order of strength. I think there were discussions about this on the mailing list around the time of the switch as well, so you could browse through that. Other than that, obviously only the people who made the switch can tell you exactly why they did that. My guess is, Werner commented on that when there were discussions here around the time GnuPG switched from DSA/ElGamal to RSA.
