Well folks .. it's simple really ...  Which version do you intend to get? Evenually I might get both, but I'm tired of legendary birds and Mew Two in X is sexier than the Frieza version (for me), so I'm going to buy X initially. I could see myself nerding out and being isolated in the basement already.

Y version

Yveltal > Xerneas

Mewtwo Y > Mewtwo X

Team looking to be Froakie's and Tyrunt's final evo, Mega Venasuar, Pyroar, Noivern, Malamar, and proably a Fairy pokemon

Gah ... I hate that I have to choose between Fennekin and Charmander since I only want one fire lol Might be the toughest decision of my life #FirstWorldProblems

I'll probably choose Fen and go with Squirtle. :/

X cause of this:

I need to know all the game exclusives before deciding that. So far X seems like the better choice.

Y
I like Yivoltiz or whatever his name is X something is cool to though

Y for me, X for the Wife!

I'm going to trade for a good plant type early lol

As for Torchic :O I love fire Pokemon so much lol I'll add it to my team for sure. But I really wanted the mega Charizard. :/

Its got to be because of Ampharos getting a mega evo. All th poke getting mega froms I would assume have to be able to be caught in the game. Some poke are probably going to be version exclusives like Mareep only being able to be caught in X and Gabite only being able to be caught in Y or something like that.

To answer the OP Ill be getting Y the legendary and the mewtwo form look best in that version imo. Not sure which starter to pick up anymore chespin's second form looks so lame may pick up fennikin depending on there final forms.

My sister is getting X and I will be getting Y. We plan to preorder the games cause apparently you can get one of the original starters by doing so, or so said my sister when she went to pick up KH1.5.

The only problem is I won't be able to get a 3DS for some time, but I can wait. Still pretty pumped for it.
