It looks like the D-pad is about full console size. But the A B X Y might as small as on the 3DS and just spaced further apart from each other, I'm not sure though.
It's pointless to worry about buttons/dpad/sticks size and positions. This is something that can be changed easily before release, and this is the kind of feedback Nintendo use from people who attented at E3. So if there is a problem today, it will not still be here in late 2012.
