I can't find the quote right now but recently Damon said they plan on recording again in September. I agree that the live shows will only make the new music they produce better.
Albarn's working on an opera with Jamie Hewitt which I think will premiere soon.
If I had to guess, after the current "The Good, The Bad and The Queen" touring is over, he'll be working on a new Blur record this summer. Possibly with Graham Coxon. One can hope.
