From what they said so far, I believe we can expect the next album rather soon. Good times
By the way, thank you for your effort in translating that interview! K+ for that.

Well arent they doing the soundtrack for Liam's film which is expected next year?

They might release an album and use that as a soundtrack or release an exclusive soundtrack but it will give us fans a new and fresh release.

They may even shock us and have two new records within the next 18 months.

Maybe they'll be as fast as Oasis in their early years? They released DM in August '94 and WTSMG in October '95. Considering Liam's statements that they have tons of songs ready a second album in summer or autumn 2012 is indeed possible.
Silence Dogood: I think that might actually happen...

I think they will do another UK tour after the festivals. Sometime between September & November. Then early 2012 look to start another record for around the summer of that year.

Pretty Green & the film commitments may delay this process, depends on Liam's thinking.

I don't see them taking 5 or 6 months off before going into the studio.

Part of the reason Oasis slowed down in album output was as the band grew they played bigger shows, in more places all over the world. Meaning they wanted more time off to recover.

The Beady Eye tour will be a lot shorter and will have constant breaks throughout so even when they come off tour they will be fresh like they were in late 09.

It took 18 months to do this record after Oasis, but this will come a bit quicker now the band is setup and songs are already been written so I reckon around a year after touring so Summer - Autumn 2012.

Possibly the same time as Noel's which could be interesting.
