Instead of writing this wall of text again, allow me to copy+paste a comment I left in Ryan's blog last week. XD
"This is coming from someone who's known to be stubborn and nitpicky as possible when it comes to any sequel in their favorite game series. I love what I've seen of B/W so far. There, I've said it.
"Zorua and Zoroark look like interesting, if a bit cliche in appearance, pokemon, what with the unconfirmed ability for zoroark to copy his opponent's stats and all.
"The starters are actually quite original conceptually. We've never seen a grass-type snake or a fire-type pig before, and even though a water-type otter has been done before Mijumaru has a completely different aesthetic than Buizel does, so it's cool. I can't wait to see what they evolve into either. I'm looking forward to seeing a Forest-themed T-Rex, a wild boar with a flaming body, and a ferocious amphibious bear. Badass.
"As for the protagonists, I love the fact that Gamefreak has officially made them older. I mean, they've been looking older every generation, and it is a little disconcerting to hear that May and Dawn are supposed to be ten. The other major implication is that the story will likely be written a lot differently than previous games, No longer are you a ten-year-old kid on an adventure just to be on an adventure. You're now going to be a teenager who was most likely summoned to adventure for some significant reason. Who knows?"
...yeah, that pretty much sums up everything I love about GenV. :P
