It's quite cool. Along with a couple of showings from Pokemon's Japan season (I watched the Ash vs. Pikachu clip, though still didn't have a clue how that came up), they also got the ending from Diamond and Pearl that's quite cool. It's in Japanese, but they had some nice words like yeah, and then jump when you get to see Hikari jumping. I sure hope they put the Diamond and Pearl ending when they show it on April 20th. They also got video songs of Ash, and also one of Hikari. I mean, these mixes were masterfully done with cool clips (won't put in for they're spoiler clips like HIkari's other Pokemon).
I have such new respect for the word jump in seeing Hikari jumping.
