Great news for MME, looks like GSM will be sensible with route structure as well. The additional routes will probably fit in with what they have served already, so NCE, PFO and PRG look likely. If GSM are going to do the longer range flights - Canaries and Cyprus, the a/c will most likely be the 736 imo, as the 733 or 737 doesn't have the range, whilst the 738 is probably a tad too large to start with.
I don't think GSM will fly to Cork or Paris, it doesn't fit in their route structure, but stranger things have happened.
