What about Greninja's general gameplay? He seems like he will be really fast, possibly one of the fastest, and that he also does moderate damage, while being knocked out very easily. He seems like he is going to involve a lot of mind games.
In one of Sakurai's Miiverse posts, he says "Greninja's sophisticated moves are extremely fun to use once you get used to how it controls!". Does this hint that Greninja may have a learning curve? Or maybe his attacks have possible secondary uses or do different things like it may depend on how long you hold the buttons. Maybe his attacks act a bit different than normal.
He also says "Another unique feature is you can move Greninja around freely while charging up". Does that mean that Greninja can move around freely while charging up his Water Shuriken? The way he describes Shadow Sneak, it seems like you don't have to charge it up, just that Greninja goes farther depending on how long you hold the buttons.
Here is a link to the Miiverse post where this is said:

Update: In a bunch of pictures shown, there were a couple dozen featuring Greninja. I don't know exactly where these images came from, but here is a link to a video showing them off.
https://www.youtube.com/watch?v=JWyqOFUet2U. They seem to show off some new moves, poses, and one in particular that has relevance to this thread at 3:48. What is that? It doesn't seem like a normal air attack. Is this possibly his Up- special or Down- special, but being used in mid-air? It wouldn't be is Neutral-special, as in the Greninja trailer, we can see the Water Shuriken be used in mid-air. It seems to cover Greninja's entire body, almost like a shield.
Do you think that Sakurai is hinting at some features of Greninja, or am I just reading to deep into this? How do you think Greninja controls?
Post if you feel like it. Thanks for reading.
