Considering that all the vehicle remoulds since MP10 (Exhaust, Road Rage, Red Alert, Silverstreak and Smokescreen) are all unique numbers the Seekers all being MP11 is odd, but at least they are consistent with their treatment of the Seekers and not flip-flopping. If they gave the new Thundercracker for instance MP-2x while Skywarp last year had MP-11SW I think I'd be a ton more annoyed with their numbering.
