Now, while Köhler has his majority, the Grand Coalition parties are losing their majority in the upper house (Bundesrat). And the FDP, the CSU's likely Bavarian coalition partner, is threatening to block Grand Coalition legislation (which they could do if they do get into the government).

At the same time, the Bavarian SPD is at least doing as if they think there is some chance of a coalition without the CSU (E.g. SPD+Greens+FDP+Free Voters).
