I do have xspec, but don't think wisp will be any success. The former team that went to wisp almost ruined the whole project. I think xspec now is back on track, with a great team. They have made progress already and the process is transparent. So lots of good things happening and you can follow it on trello. Personally I would wait to see if they keep on track with developments before buying more. When it comes to the fork and wisp, I've no idea what they are up to, and wouldn't pay any attention to that, untill they show a product.
