This 'MPL' thing will be mostly simulator based. Hence some of us contemptuously refer to it as the Microsoft Pilot Licence.
Due to the extensive need for expensive simulator time, it will be very expensive for anyone not directly sponsored by an airline - and may not even give pilots a SEP Class-rated PPL.
It will be purely a co-pilot licence; Lufthansa, who currently claim to train their pilots to a higher standard than the JAA require, are championing this......
Personally I think that it should be consigned to the rubbish bin. Fair enough to train people to CPL/IR on a complex single and then to develop them using simulators for multi-crew IR and Type Ratings (although the proposals call for no less than 12 landings for MPL-'trained' pilots to take their Type Rating Skill Test) - but less than that time on real aircraft? NO WAY!!
