Oh, Super Mario Sunshine... after all this time, it still stands proudly on my list of venerated titles. I've always hoped it would be remastered someday. When Nintendo officially declared that Wind Waker would be revamped for the WiiU, that seemingly futile hope of mine was given a bit of reason to ground it. Seeing as it did well, I thought they might use the success of Wind Waker as a gateway into remastering the classics of my childhood. They also restored its precursor, Super Mario 64, for the DS; this did fairly well, too. Why not resurrect its whimsical successor from the tropics?
They have the means to make it, and I'm sure it would be popular — I know I'd be the first in line on launch day to pick up a copy — but at this stage, it seems a bit unlikely. The emphasis right now seems to be on the new – the launch of the New 3DS and New 3DSXL, new concepts and games for the WiiU, creating amiibos and DLC for existing and upcoming titles, their entrance into the mobile gaming industry, the NX, and so forth.
I really hope I'm wrong because it pains me to type this, but I don't see it coming to the WiiU or 3DS any time soon. Perhaps they'll revamp it at a later date or for the NX, but for now... it seems as though we'd better keep our fingers crossed and hope for the best.
