Spin might be a bit overrated. No doubt it's very useful on the slow and turning tracks of the Subcontinent, but a lot of the Asian batsmen are extremely adept at playing spin, more so than pace, and dew is bound to be a factor at most of the grounds, rendering spin pretty harmless in the second innings.
If anything, I think pure pace (Malinga, Lee, Steyn) and reverse swing (Zaheer, Gul) will prove to be the best wicket-taking options. Even swing bowlers with the new ball could be a handful on certain pitches (Kulasekra, Praveen, Anderson)
Canny medium pace cutters and changes of pace will be fairly useful too, especially in second innings when dew makes it trickier for spinners. Guys like Collingwood, Trott, Hastings, Razzaq, Pollard and Styris could be more effective than expected over the course of the tournament.
