I didn't quite understand the move from 148 to 141. To me it would have made more sense to move ESPN2 to 141 and ESPNU to ESPN2 location after the move of ESPN2. IMO, this would have been a better solution.
An ESPNU alternate channel would be my first guess... or, if they are seriously going to convert ESPN Classic into an ESPN Soccer channel, then 148 is right before Fox Soccer Channel... Other than that, don't know... Gol and MLB seem very unlikely
