I can't see why Chouji would live .. I mean they made such a *HUGE* dramatic deal about how deadly those pills were, then had him go down in a big blaze of glory complete with flashbacks, and went even further with the butterfly symbolism that made Shika look even more dour than usual...

Bottom line is, if Chouji IS alive, it would totally cheapen any sense of drama or danger that the series has .. it would just get cheesy fast.
