Retro's retirement gift to Reggie has fans looking for hidden clues

Reggie put up another tweet showcasing a number of retirement gifts he's received, including a piece of custom art from Retro Studios. It's that piece of art that has fans salivating at the thought of teases for things to come.

First up, we have the artwork for Samus. While the details are a bit iffy, it seems most fans can agree that the design of Samus is new. The head-portion seems to combine the visor from Other M, but the helmet of the Prime series. There's also a slight difference in the Arm Cannon below the elbow. Is this all just artistic license, or is there something more to it?

Moving on, there's also a mystery robot-like hand in the image. This is the one that's really confusing fans, as a specific point of origin can't seem to be nailed down. It doesn't help that the Mario statue is blocking the way either! There was some dicussion that the hand is from Metroid Prime: Federation Force, but that was quickly shot down for a number of reasons. That leaves us with no clear-cut explanation as to what it's from!

Last and least, people have noticed that the font in the image comes from Banjo-Kazooie. Some are hopeful that means something, but I wouldn't put much weight in that.

Well, Nintendo sleuths, what say you? Can you glean any information from this, or is everyone diving a bit too deep?
