My guess is that we won't see the next age until after the next Winter of Ages, so February/March at the very least. To be honest, I doubt there will be enough late game players to support a new age even by then, since they seem to be so stubborn about speeding up the process for any newer players. Considering we're eight months into CWA and it's even more piecemeal than atomic was in regards to upgrades and new features it could be a very long wait indeed.
They really could stand to FINALLY figure out a solution for the maxed out market/mills issue that's plagued this game for so long, especially given the recent frequency of wall discounts. An exchange, alliance bank, bio-fuel plant, any sort of resource sink would be most welcome. Some people will have been sitting on full resource storage for nearly a year even in the most optimistic of Space Age scenarios. Not a gamebreaker, but not something they should have let fester for as long as it has either.
Anyway, time will tell.
