A good enough PC to run TESO would cost you a lot less than the console.
I would think the owners of those guilds would still welcome console players, but just have 2 split sub guilds: one for PC and one for console. Well, an idea, that is.
Probably just too soon since the announcement. Just need to wait a bit for console guilds to form up. Probably wouldn't hurt to go to those recruitment links and post asking if there are other console players looking for guild, might make a few contacts to get the ball rolling so to speak.
Use the same procedure for now as for PC.

Submit your guild for link in the above thread to Zenimax Online or ask on one of their social networks.
