Never heard of NST before? NST in an acronym for Nintendo Software Technology, a Nintendo developer founded in 1998 to make games for the western audience, but lately they have been making Mario vs. Donkey Kong games. Such a shame.  

But if my theory is right, they might just be the one making the next 3D Sonic game! You see, in 2012 one of the three creators of Sonic joined NST! I'm speaking of  Hirokazu Yasuhara, and he's not only a former creator of sonic, he has also worked on Jak and Daxter, not to mention Uncharted. Seems rather likely to me that they started making Sonic LW in 2012, which should fit nicely with this. I do not doubt that other teams, more specificly the galaxy team will be in front of this game too.

What do you think?

PS: NST have also been making other games like the legend of zelda master quest/collectors edition, metroid prime hunters and 1080 avalance.

Title is misleading; this is you purely speculating. Would be nice if true though.

Fixed. And yeah, they need to start doing something else than Mario vs. Donkey Kong. Maybe start making those western titles they were supposed to.

This just reminds me that Yuji Naka, wich is a great talent is sitting beeing wasted on some lame ass small company he made for himself.
I miss the days of Yuji Naka and Yu suzuki, between other great talent that SEGA used to have.

Totally! It's such a waste!

I bet NST secretly stands for "Nintendo Sonic Team". That's all the proof I need right there.

I still haven't seen where Nintendo is directly involved in this project. can anyone get me Link please?

THIS!!

I'm looking, but I can't find were I read it. Anyways, it's still a theory, and Nintendo being involved isn't too far fetched. 

I agree; they're publishing Bayo2, so they're probably on good footing with Sega because of that...
