The wording in the U2.com email for the Q&A was interesting:
"Catch the band live from the studio...
Answering your questions"
Either teasing people by inferring they may play, or deliberately leaving it open. Perhaps they have been rehearsing early so they can play something for this Q&A?

As much as I'd like that to be true, I think it just means this live Facebook thing will be broadcast from a studio (Where they're probably working on SoE). It's likely just a convenient place for all 4 of them to be at the same time, plus publicly presents them as rehearsing/recording. I doubt anything will be played.
