Ryan Tedder's touring schedule with OneRepublic is pretty busy this year, but there is a 2 month gap between the European/US legs taking place between the end of March and the end of May, and then another month long gap in July. Maybe he will work with U2 during these times.
Danger Mouse's Broken Bells schedule seems to be freeing up after April, with them only playing the occasional festival throughout the summer.
My guess is Danger Mouse is still going to be the principal producer, Tedder has been brought in to polish a few of the "singles" when he has time, and Epsworth is more or less engineering, mixing, and doing some light production while DM is on tour.
The interview with Bono at the Oscars lead us to believe they had some kind of masterplan involving 2 albums and all that. Now nothing? Now just more indefinite waiting? Something went haywire in the last couple weeks.
