Nope, no way they release it in April. May has traditionally kicked off the summer blockbuster season and Disney will certainly want to release it during one of the peak box office revenue periods.
Also the new Avengers logo released at comic con just said "Summer 2015" so they may push that back for a May release of ep VII like they originally said they were shooting for. Or they could release one on May 1st and the other at the end of May.
