Besides the Pokemon X/Y 3DS XLs that came out last week I don't know of any bundling (they may be scared of alienating those who want the regular 3DS and/or XL by dropping the 2DS price even further by bundling)
Gamestop has a preorder bonus of a poster with each version and some sort of Pokemon timeline book if you preorder both. Pretty lame actually.
I was wishing my sister's kids were old enough for these (she has 3, - 3,4 & 5) and that I had the extra money right now - maybe if/when Ruby/Sapphire remakes come I'll grab them then.
