I was going to put Foo Fighters as a prediction but there's a misgiving on whether they're going to be on pause following Dave Grohl's misbehaviour. I know there's a rumour they're still in talks on touring next year anyway, but there's enough doubt to make me put LP instead for now.
Thinking about it, are Linkin Park rumoured for anything? If they're announced for Download next year then they'll be an absolute no for R&L.
