Pearl Jam Coming to Download Festival 2013?

Alright, even though it remains unconfirmed, we'll go ahead and take this from rumor to fairly likely ...

It seems like Download Festival partner, Vodaphone, could barely contain their excitement and made a Facebook post touting Pearl Jam as one of three headliners for next year's Download Festival in Donington Park, Leicestershire from 14th - 16th June 2013.

"Vodafone customers can buy their tickets to Download Festival 2013 now, 48 hours before the general sale. Pearl Jam, Iron Maiden, & Ramstein fans, hit LIKE & get yours now!".

Does this mean that Pearl Jam will be done with their tenth album by June 2013?  Well, that would more or less jive with previous statements about the next album.  Still, nothing (album or festival) has been officially confirmed.
