Ever since former Sonic Team general Yuji Naka started his own company Prope back in 2006 it's been quiet, but now it seems we are about to get some news. Sega is part owner in Prope, and will therefore most likely publish whatever Prope are working on.

In ten days we'll find out more.
Check out the teaser site.
