One small change with more than 95% of the vote counted: it's CiU 48, PSC 37, ERC 21, PP 14, IC 12, Ciutadans 3.
Further notes: Maragall didn't look at all happy or too sober up on the stage while Montilla was claiming victory; Montilla's line was that CiU failed in its attempt to get more votes than the Tripartite. Zapatero's extensive campaigning in Catalonia does not seem to have done the PSC much good. CiU certainly did not do anywhere near as well as the surveys said. The PP is out of play; no one wants anything to do with them, and I imagine Ciutadans is in the same boat.
