Hmm, what do people think about this?

That's the icon selection screen... not much to speculate about, but...
-Nothing is blurred, so any "secrets" would either be above or below the visible icons
-They've scrolled down just a bit to hide at least the first row of icons (Mushroom, DK, and Triforce emblems are hidden, and there's no sign of the Animal Crossing, Mother, or Smash Bros emblems... those six would fill the first row...)
-The playable characters are all in a row, of which we can see both the beginning and the end.
-Both Samus and Zero Suit Samus have separate icons, as do all 3 of PT's Pokemon, but there's still no sign of Sheik.
-Judging by the position of the scroll bar, there may be several rows of icons below what we can see (although those could easily be all Miis).
Any thoughts? Not much to go on, but my interpretation is: all of the starter characters have been announced. Anyone not in that screenshot will be unlockable, or not in the game at all.
