So here is some news from Serebii.net
Pokémon The Series: XY

During the episode of the anime today, some further details of the upcoming series Pokémon XY were revealed. Within this, it showcased that Ash knew Serena when he was a child, and showed Bonnie and Clemont helping Ash when he was falling. It also showcased Ash standing off against the rampaging Garchomp on his own as the media watched.
It is also revealed that there is a new design for Officer Jenny, while Nurse Joy keeps a design similar to her Unova design. In addition to that, it is revealed that Bonnie is hunting for a wife for Clemont, and she also holds onto his Pokémon. Clemont has a robot arm called the Aipom Arm in his backpack. Clemont refuses to battle Ash at the Lumiose City gym because he has no badges.

So what are your hopes for X and Y now? Its pretty weird that Ash knew Serena as a child and he is meeting her in the SIXTH GENERATION. Nurse Joy 'aint changing herself again but Officer Jenny is.. So what do you think next will happen?

Its like the Advance generation series,as Ash is having 3 friends and will form group of four.I have seen the trailer,they used a slightly differenent animation which is more enhanced.

Yes. I am confused a little bit. Can you help me out? Can 'chya tell WHAT Pokemon series is going on Japan? Declora Adventures or the Kalos anime has started?? It'd be great if you can tell what is going on Japan..

Declora Island or BW series will end on 26th of September.On 2 October there will be priemere of Pokemon Origin after that there will be a two week hiatus and thus Pokemon XY series will start on 17th of October,2013 right at their time on thursday.
Hope I helped.

Thank you! So that means that the videos of Ash and Serena,Bonnie etc. are just trailers?

Serena,Bonnie and Clemenot are the travelling companions of Ash Ketchum in Kalos region.They will join Ash in the begining of series.Anyways to introduce things you always you trailers.

Aha. Thanx for information

Another thing that Wobbafutt is going to be the permenent part of team rocket in Kalos

Yes I know. I wish he makes a good comeback!!!

Wobba Wobbufutt.Jessie:Return to PokeBall you headache.

Wobbufett: (eats James's head) Wobbafett!!!(delicious!)

I actually wanted to post this but was too late for that.

Now hoping that Ash is no more a "KID" as in previous generations and is a teenager now with good knowledge and abilities than before.

It is ridiculous that Clemont being age same as Ash is having sister with him to find a wife XD hahahaha

Serena is known to Ash but is never mentioned in any where till now.

This generation brings a lot of mysteries for us. Let us solve them together over here.
