After the sexist rants/controversy that came up over the heels just from the Other M render alone before the game even came out, I hope for SSB4's sake that she has the same heels as Brawl, which weren't too high.
If Sakurai gave a **** about angry media and fanboy rants, he wouldn't have based her Power Suit on Other M. I think he know the haters are always the loudest ones.
The fact that everything Metroid/Samus so far is based on Other M means that Zero Suit Samus will likely be based on Other M as well. However!
Do you remember what happened to ZSS in Brawl? I'll show you:
Zero Mission was her first game. Even though she appeared in Prime 2 and 3, we never saw her from the back in those games. And the difference between Zero Mission and Brawl is huge - literally.
Zero Mission: her butt and thighs look plump and fat. There's a huge difference between her upper and lower body, her upper body is in shape, her lower body is very untoned and soft. It was very surprising to see that someone as strong as Samus actually had a fat butt. Not that people were complaining about it - most guys like curves and feminine features (fat and flab in the right places). Also note the thonging lines on her Zero Suit.
Brawl: they based her on Zero Mission, but they trimmed away all the flab. Her butt and thighs match her upper body much better, and they look sleek and toned. So obviously, while they based her on Zero Mission, Sakurai still made changes to her body. Note that the thonging lines have been changed as well.
Other M: her waist is a lot longer than both Zero Mission and Brawl. Her butt, however, is once again big and plump. Not quite fat as in Zero Mission, but still plump and soft. The size is once again the same, but it looks a bit firmer. Also note how the thonging lines now are completely gone and replaced with less suggestive lines.
What does this mean for SSB4? Well, they'll probably base her on Other M, but my point is that they might change her body, especially her butt and waist, to suit SSB4 - whatever that means. I actually doubt she'll keep her big, plump butt from Other M, it'll most likely be trimmed as it was in Brawl compared to Zero Mission. Her buttocks from Zero Mission and Other M are ripe for jiggle physics - such large amount of fat don't keep still when one move. That's another reason for Sakurai to use the more slender and sleek body from Brawl.
It'll be highly interesting to see Zero Suit Samus's return. Also, I wonder if she'll keep her whip?
