I'd very much doubt it this year. They are playing Download obviously and it's not particularly common for bands to do both of them. Coupled with what has already been announced for R/L I can't see where they could play. Also, given the fact that they've played 4 times in 5 years, it's probable they won't this year, just for a change!
They've played both the lock-up and NME before, in years gone by...
