I wouldn't see Mattel skipping SDCC as, A) even possible, B) a good thing on any level. SDCC is a great opportunity for open publicity for ALL of Mattel's product offerings, not just MOTUC. So whether they show up to tout WWE, Mattycollector, or Monster High Dolls, Mattel is still going to be there doing their thing. Not only that, but it's great to see new and old MOTUC related product in those cases and rub elbows with fans and look-e-lou's alike. So I say as long as MOTUC is still going (which fortunately at this point it is) then Mattel should keep a presence at SDCC.
