id Software animator Fred Nilsson has updated his .plan to offer downloads of a couple of maps, one a Quake III Arena pro map called pro-q3tourney7 that's a polished up version of one of the maps that was cut before the Quake III Arena release. The other is a Team Arena map called mpteam9.pk3 that's an evolution of q3tourney6_ctf/mpq3tourney6. He says this latter map is the one they play at id when they squeeze in some game time, so they might try to play some matches on it at QuakeCon.
