I mostly agree with him. The director and writing staff are all different. Doesn't appear to have so much as a single crossover staff member of noteworthy significance, unless you count the Pillows who we've only heard recycled tracks from the original out of. Bringing them and returning voice actors back won't mean a whole lot if it's no more than a tacky cash grab.
Like, no guarantee it will be, but the lack of any staff connection makes it highly suspect.
