Pokemon Movie 11

Yeah first post! The japanese movie website has revealed the eleventh pokemon movie. In this picture it shows a GIGANTIC regigigas and since there is flower fields it may introduce shaymin. Here's the picture:

This is what I think the movie is about, I think regigigas will be locked in a chamber (like at snowpoint) and it needs the regi's to escape. Then shaymin finds ash and the crew and they help. Yaaa... maybe not, but that's what I think it's about (maybe a little off). See You next Time!
