Return Of Alan Wilder?

Is Alan Wilder returning to Depeche Mode? I wouldn't be surprised. Back on February 17, 2010 he shows up at the end of a benefit concert DM participated in. Then today I read on the DM site that Alan will be releasing a “new” Recoil album of old but “remastered” material. Alan's departure from DM was acrimonious but it was also in 1995. I really don't think he'd fully rejoin the band, even for just one album but I wouldn't be all that surprised if he came back and worked on a song or two that were included in the next album.
