The Anderson-Rabin-Wakeman project has been on and off hold for 20 years, ever since the Union days, and even when it's "on" it's still only "on" to the point where they'll admit that they're trying to work out the schedules. The three of them have still never gotten together. I get the sense that it's something they'd all love to do, and that the media likes to ask them about, and they'll never say "never". But as a realistic possibility, no. Again, these guys can pretty much do what they want, and if it was important enough, they'd make time to do it.
As much as I love Anderson and Wakeman, and what Yes music is like with them in the picture, I too would rather have Steve in the band today than either of them. Clearly, neither Anderson nor Wakeman are into it, and I'd rather have someone who wants to do it. Yes is Steve's baby. Anderson and Wakeman are both total flakes and do whatever they want. If they both came back, that's a tougher question, but it's not gonna happen anyway. Rick has pretty much said that he's done with Yes. He's comfortable with his home and his regular gig in England and has no interest in getting back together with Yes. They've asked him, many times. Now, each of those times, Jon was not in the picture, which I'm sure makes a difference, but again, Jon just won't commit to it. So it's not gonna happen. (Meanwhile, they'll both whine about how it's not "really" Yes without them.)
At this point, Yes has a working lineup and have a tour scheduled, with all five on board. They also announced a return to the studio later this year, and it was announced before Asia made a similar announcement. Geoff Downes is in both bands, but he's always struck me as a pretty cool, upfront guy, and I don't see him backing out of either commitment. We should see new Yes and Asia albums both by next year.
