(Rumor) StarFox Metroid Crossover?

StarFox Assult mock box art for Wii U

A rumor is spreading across the net that Retro Studios is working on a StarFox and Metroid crossover game for the Wii U. Even though it may sound good at first the rumored plot doesn't appeal to me.

The plot of this rumored StarFox and Metroid title is that StarFox goes into deep space and crash into Samus's ship, Samus falls to a nearby planet and loses all her powers. She then has to go around the planet for some reason while trying to restore her abilities.

The game switches off between controlling Samus and Fox. When controlling Fox you are apparently trying to get to the planet, from what I heard anyways.

I tend to dislike when developers try to make two games at one like this because usually they both end up suffering, even if one of them turns out to be good because it's with the other it ends up being hated, such as Sonic Unleashed for the Wii which had awesome day levels but because of the night Werehog levels people tend to throw hate at it.
