I don't think Nintendo will allow them to do things like this to Samus. Even though they're being more lax about M rated games on their systems, they don't make any themselves, and I doubt they'll let Samus suffer any major indignities while in her Zero Suit.
This kind of "feature" is really unnecessary. It's development time that could be better spent working out bugs or tightening core game play mechanics.
If you REALLY MUST stare at a pair of bouncing breasts, you're on the *gasp* INTERNET... where you can do so until your heart's content and not have to cough up $50 - $60 for it!
