The long-awaited Xbox Live Arcade port of Quake III Arena - Quake Arena Arcade - is on show at QuakeCon in playable form, suggesting an impending release.
Reports from the Dallas show also bring news of a Nerve Software-authored XBLA port of Doom II. It too can be played at the show, which suggests it's not far off either.
id Software has previously collaborated with Nerve on the XBLA release of the first Doom game, which came out around three years ago and recaptured our hearts.
Quake Arena Arcade, meanwhile, was announced at QuakeCon two years ago and is another collaboration - between id and Pi Studios.
