we probably should wait for a response from Anet, once GW2 is going like it should be, then some more devs may return to GW, and their resources could be high enough to create more for GW, so they got 2 games going on
also, i havent quit yet, i'm even buying a char slot and merc slot to create 1 wintersday based char, lol
if Anet's doing well, it wont be the question "is it possible to get a GW expansion?", but it would be "will they sell us another GW expansion?"
if they would, i wouldnt mind having an offtopic one, not doing more with GW and/or GW2's lores, but 1 more made to have fun in (and enemies on HM having pve-only skills, lol)
but it all depends on how well their resources go
and of course the amount on GW players, as they have to sell it (giving away is nice, but would make it harder for their own resources) to as many as people as they can
i know several people playing both or just GW2 for a long time may also return, but since GW2 is growing and gets expansions (maybe even campaigns), its hard to see them return for GW while getting more for GW2
so it DOES matter what happens with Anet's money with both GW and GW2
its also the only reason i hope GW2 goes great (much better than it goes now), so that GW gets more also, as i dont care about GW2 for myself
but i have faith in them, and they may reply to this question, about whether or not it COULD happen, i've seen john stumme answer questions people had about GW
so... to increase the chance, everyone who likes GW and will still pay for GW stuff "let friends/other people you see in RL and/or internet, know that GW still can be fun when finding enough friends and/or nice guilds
i think Anet should somehow "announce" that GW will keep going, and is being worked on, once GW2 has enough to let them reduce the GW2 dev team to make the GW dev team some bigger
i guess we gotta wait for that time, but i have faith in them (and its the only MMO team i have this much faith in), as stumme has done alot good to GW before GW2 got released
