At this point, I think they will do something since so many people didn't get their eeveelution (not to mention all the really young kids they disappointed too). After this, I'm not really looking forward to more events like this, if they do they should make damn sure there are no glitches! (or they could just give them directly through Dream World without having to play anything on the Pokemon site) >.>
