Well, it's nice to finally have more Ken Sugimori artwork. All of the poses are pretty much exactly how I envisioned them (since most of them match their sprites) and the way he drew them (shapes, details, etc.) matches how I thought he would, so I guess it was less of a treat than it could have been. xP
The art for Yakon (or whatever his name is) is pretty funny. Always busy, that tycoon!
Anyway, it's a shame we'll be getting the artwork for the non-event Legendary Pokémon from guidebook scans instead of Coro Coro leaks. Coro Coro always gives them such cool pages. (Of course, they'll still get that treatment, but all of the hype of seeing their art for the first time will be gone.) Regardless, those are the pieces of art I'm looking forward to most.
