My conclusion is the opposite. If Daishocker is still around, why is Apollogeist considered the "final villain" here? He's the final villain because he wasn't in the Decade movie and so survived even after most of the Daishocker was defeated. Think about it, in this episode, he didn't even summon any Daishocker troops, just used the ones from this world.
Besides, if the movie happens after next episode, Daiki will have to leave their party after joining in the Amazon world scene... only to join again at the end of the movie. That seems rather strange.
