ok so this is what i think
ash and co. are right now in sinnoh
and soon to be facing fantina the 5th gym leader
so i think this
another season and movie(season 3 and movie 12), then a new series will uphold
after the next season after this one ash beats all 8 gyms and almost beats the league like always
then there are my thereos

1. if a GS remakle does happen ash will do the platinum battle frontier in johto,
the season finale will be ash fighting palmer and winnnig
after that season.....
they will go to the northern island of sinnoh
there will be like mini gyms and stuff like that
the season finale will be stark mountain and heatran in a 2 part special(which means heatran wont be in a movie but a special like raikou)
after that season ash and co. will go to the 5th generation.
we are now on season 12, so that makes seasons 13, 14 and 15 then season 16 season ill be ready
now for my second theory

2. ash and co. will have 1 more season in the sinnho league
ash and co. go to the northern island and have the battle frontier there but all scattered instead of it all in 1 spot
heatran will be the special 2 part ending
then the 5th generation will be next or something will happen with the johto region(then 5th gen.)

Yup

Season 12 will finish Sinnoh and will have Platinum Stuff as the storyline
Season 13 would be battle frontier whether in johto or not
Season 14 will be 5th gen aswell as at least 15 and 16

And the 12th movie will have Arceus in it which finished the Manaphy, Darkrai, Shaymon etc event legendary order that has happened recently. The movie will also finish the Dialga, Palkia, Giratina storyline and explain it all.

i think the 12th movie wont have arceus
i think it will be dialga, palkia, giratina and cresselia
then the 13th movie will involve acreus
after that the 5th generation will begin

that's a good thought. It's possible that would happen.

But then again at the end of the 11th movie in japan they said that the next movie will be called (japanese title:) Dialga vs Palkia vs Giratina vs Arceus

It is unknown if this is completely true but it seems likely.

We will probably find out mid next year when it starts to be scheduled for airing in japan.

well that was a rumor
and what i heard was it was called dialga vs. palkia vs. giratina

then on the internet someone said it has vs. arceus and i only heard it on the interent, not on youtube or from any officials

I heard that it was gonna be Dialga vs Palkia vs Giratina as a working title and that vs Arceus will be added when Arceus is revealed.

Thought according to all the evidence being that Arceus will be the next main event legendary after Shaymin, that strongly says that Arceus is gonna be the next star.

everyone should think about it. The greatest pokemon ever. on the big screen. the film would be awesome!

well obviously arceus is after shaymin and it will be in a movie
but after arceus will be directly to 5th generation
its been only 3 years so far
a little less
this is why i thin k what im saying

Well the 12th film will be out in japan midn next year and in america late next year maybe early 210. Then if the battle frontier isn't in sinnoh, then arcues might not be in it. I think that the 13th film will be battle frontier in the battle zone island and with Heatran. After all battle frontiers are a filler season and the evidence does point to Arceus being in the next film. I guess we will have to wait and see. Arceus aint even revealed yet so who knows!
