Primero, did anyone catch if Wonderwyce was an espada? I know he's not in any of the pictures of them but it makes no sense that using Hyogoku and him being the most recent arancarr that he not at least be stronger than Yammy. Urahara certainly took him more seriously than he took Yammy and it was already stated that Yammy's position as number 10 was possibly in jeopardy once his arm was removed. Could Wonderwyce's promotion have been held up by Ichigo & Co.'s invasion?
Segundo, Who do you think is going to join Ichigo & Co from the Espada? I think theres (as usual in shounen manga) a good chance one of the remaining espada doesn't agree with something Aizen is doing or just doesn't like him (i.e. Grimmjow).... Traitors anyone? I've got my hopes on Halibel as she seems the least interested in fighting.
