Yes is going to quickly tour South America this month. There are shows already booked in:
Yes fans from South America haven't seen the band since 1999 so I'm sure they're going to have a great time!
PS: Before/After the tour the band is supposed to be working on a new album. So only good news today :)
PS2: My sources were the sites of the respective venues.
Only yesterday, 06/11/2010, (11 days before the first show!) the tour was mentioned on Yes World (the official site) and they even say new dates may be added!
I've never seen a tour in my life that was so carelessly organized as this.
November 10 update: two more shows, in Brazil (Florianópolis, 27/11) and another in Buenos Aires (3/12)
