I... Honestly really don't like the starters this time around. Like, any of them. Fennekin is a little too cute for my tastes, and the other two just look silly in my opinion. Granted, we haven't seen evolutions yet. I'll probably end up judging based on evolutions, too, because... OK, partially because some evolutions just look cooler than others, but mainly because if they rehash Fire/Fighting again I'll refuse to pick it just like I did with Chimchar and Tepig. It's ultimately between Fennekin and Froakie, due to my eternal lingering distaste for Grass.
As for everything else, the X and Y can have many meanings. Chromosomes, sure, but also the Cartesian coordinate system, also algebraic variables, the possibilities are endless. The two new Legendaries shown... Well, I might like them in the games proper, I guess, if they get a good mythology behind them. It's too early to judge the worth of them; I thought Palkia and Dialga would be really interesting when I finally got into Gen4, but they were overshadowed in my party by Giratina; conversely, I wasn't feeling Gen5's Zekrom until I actually had Zekrom on my team. I can say that in my opinion on the designs alone, the bird is too obvious in its reference to the game's title while the deer's antlers are rather distracting between their large size and their multiple colors. The protagonists as we see them now both look really good; the male is a step in the right direction as far away from the B/W2 protagonist as you can get while still being as similar as possible to the B/W hero (which is in my opinion a good thing, since the guy in B/W was cool while I seriously disliked his palm-tree-haired replacement in its sequels), and the female... Well, the girls in B/W and B/W2 were so awesomely gorgeous that they just couldn't keep that up in the direction they were going, so it makes sense that she's so different. And I'm fine with her, the fanart that I've seen thus far has made her look pretty enough. Keeping in mind of course that we don't have official images of them aside from glimpses of the in-game character models, and of the two we've gotten a far more clear look at the male, so that when we do get a closer look at the girl, she might be far less pretty than I thought she'd be, or she might impress me by being as lovely as the B/W2 female.
Oh, and since we're apparently setting this generation in PokÃ©France... Is there gonna be a surrender option in Trainer battles? Do the people there eat Froakie? Are all the Legendaries gonna all run away when you see them?
Overall, I might not like it as much as I liked early pre-release revelations of B/W, but I'm pretty sure that it's gonna be good overall, since it's a brand new PokÃ©mon and those guys haven't put a turd in the main series yet. Well, OK, except maybe Yellow, but they still didn't know what they were doing in Gen1.
