So, to start with, we have the cool 3D graphics and gameplay. This is about as big a step forward as ruby and sapphire were for gold and silver (although, I'm assuming we can trade between gen V and VI).The graphics do look somewhat different, but this is not a bad thing, finally we have proper 3D battles like we saw on Pokemon stadium on the N64 13 years ago.
Next of course, we have the starters of gen VI themselves.There has already been some far out speculation, which doesn't entirely sound all that bad. We all know of the usual typing of grass, fire, water; how one beats one and is weak to one. Well, there is another three types that exhibit similar traits. Fighting, dark and psychic form another loop where fighting beats dark, dark beats psychic and psychic beats fighting. The only difference in this is that dark is immune to psychic, not just super effective.
Due to the second attacks each starter show in the video, people have claimed that they exhibit the second type of one o the three:
Chespin appears to be Grass/Dark as it's second attack shows it using a night slash like move.
Fennekin appears to be Fire/Psychic as it's second attack shows a move similar to confusion.
Froakie appears to be Water/Fighting as its second attack appears to be close combat.
Of course, these are first impression speculations and will most likely not be true.
Lastly we need to have a look at the legendary pokemon shown, Xerneas the X shaped elk badass and Yveltal the Y shaped bird demon phoenix thing.
How cool do they look? Xerneas looks like some badass world saving elk embodiment of nature and Yveltal looks like he doesnt care what he does, nobody can stop him, they just watch as he destroys your family and everyone you love.
Alright, there we have it, now go out and buy a 3DS and sit patiently until October when they get released worldwide.
