Really, the only choice I _wouldn't_ select in the poll is "Not going to purchase" because I'll probably do all of the others eventually.
I'm initially going to buy it as a reference, due primarily to the fact that I've currently got a MT-variant game going and the players are happy with it. Should they ever look for something new, but similar, I might suggest T20.
I'm also involved in an area RPG club, and they sponsor a d20 "Guildworld" where players can run the same character in multiple GMs universes all using the d20 system. Should enough people show interest, we might set up something similar for T20, and who knows which timeline we'll set that up in.
At a convention, I might run an adventure as a one-shot set in TNE's timeline, or perhaps M:0, whatever works best.
So, essentially, my choice works out as "All of the above."
