The most interesting thing about Gaga's Superbowl set is going to be Telephone whether it gets performed or not.
There is a high chance that Beyonce wont do the SB for a second time in a row so if Gaga does do Telephone, it will be interesting to see who she features in the song. It will also be really funny if she does the song solo.
If she doesn't do Telephone, it will be weird because it's commercially one of her biggest hits.
