Yeah they added some new backgrounds but those textures everywhere else look exactly like the N64 game. Sure they have a higher resolution, doesn't mean the textures themself are high res. It's like putting a DVD into an upscaler and then calling it high def. No, you need the actual detail not just an increased resolution.
On top of all this, if the game doesn't have significant improvements it won't be playable. If it's not dual stick for example, not playable. Gameplay wise, it needs to be tightened up a lot t meet today's standards.
Even then, it would still not be an exclusive. And no Osyris, Sony and Nintendo are not screaming "exclusive!" on everything they announce. It's Microsoft doing that, and stamping their boxes with "only on Xbox 360." To me whatever they say on that matter is meaningless though, they just love to beat their chest. The funny thing is that even first party Sony and Nintendo games aren't stamped "exclusives" even though they never end up on other platforms. I dunno, it just makes MS look really childish and petty, especially in cases like this where it's clearly not exclusive at all.
