If O'Neill intends on starting Keane come September then it'll be interesting to see how he works the formation to use him without reverting back to good ol' 4-4-2.
MON has already been quoted as saying he sees no reason why Hoolahan and Keane can't play together with Keane alone up front. It's very likely that Keane/Long will become interchangeable for the qualifiers depending on the opposition.
I'll be at the game. Looking forward to it - good crowd expected.
