I saw them on their current tour (which is now over - they're heading to Europe to continue the tour).
The only original member of the band on tour right now is Chris Squire... Jon Anderson wasn't able to go on the road at the start of the tour, and rather than postponing it, they found Benoit David, the lead singer from a Canadian Yes tribute band. He's really quite good, and an extremely nice person. One of my co-workers who went to the same Yes concert told me that Benoit was actually sitting next to him and his wife in the audience while Asia was doing their set, and he was very nice and personable - nobody else recognized him.
Bill Bruford announced a while back that he would no longer be going on the road... While Jon Anderson is now capable of touring, Benoit David is still on tour with Yes, and Rick Wakeman's doctor wouldn't let him go on tour... Let's face it, the guys are getting older, and touring is a very hard life. The lineup that is on this tour was Benoit David on vocals, Chris Squire on bass, Alan White on drums, Steve Howe on guitar, and Oliver Wakeman (Rick's son) on keyboards. If you want my personal review of the concert, check this out.
The reason I decided that I was going to get the VIP tickets ($400) was because this may be the last opportunity I will ever have to see Yes. With the death of Richard Wright (keyboardist for Pink Floyd) last year, and the health issues for Jon, Rick, and Chris (he had a blood clot in his leg during the tour, and they considered canceling, but after medical treatment and a short rest, he was given the OK to continue), I sort of doubt they'll be touring again. It was an amazing show, and I'm glad that I had the chance. I've never been so close to the stage at a concert: Front row, center.

Yes appearing on the same stage with Asia—Steve Howe must have been torn!
