I think it should stay open...keep the dream alive and all that.
A lot of people love and miss the speed of WFA/Q3 (me included), along with strafe jumping. Is is possible to update Q3 source code to use higher poly models? Does D3 (source coming soon!) have the strafe jumping still there, or at least the speedy feel? I can't remember.
Q3 was really one of the last engines that were accessible to hobbiests wanting to make a mod/game. It's just too time-consuming to create content for games these days. It's a shame.
Anway, I believe there is still a place for WFA gameplay, maybe even a market for it.
