Wow...I finally managed to get back on. I enter the Brawl Character Discussion forum, and there were suddenly several more (strange) characters added.
My impressions, if anyone cares:
Those videos were great to watch. This Kirby is definitely better SSBM's Kirby. I might be able to actually use his specials. His hammer moves come out significantly faster-->O_O. The hammer moves have shorter range, but at least I can probably use it more often. Final Cutter speeded up. The Stone looks usable. For whatever reason, those Japanese did not actually test Swallow.
Kirby is now more manuverable in the air. I was actually surprised by the speed. Is U-air has been (slightly nerfed), but B-air (my main killing move) is about the same, if not better. F-Air seems just as lovely. Kirby's edgeguarding is going to improve...
Kirby actually did F-throw on Ike at the beginning and managed to hold on (and Ike had about 8%!). D-throw does nice damage (a whopping 13%) but the opponent (in the Kirby ditto match) was still knocked back too high.
Kirby's dash attack did not have Kirby ending up off the stage (it just finished at the edge), but I honestly do not know if the dash attack is better. I will have to look at those videos again.
Tilts seem just as good and I wonder how low Kirby's crouch is this time.
Thanks to the Japan players for posting the demos. Those players were awesome. Kirby definitely has potential.
