It is here soon so I thought it was time for a Catch all!
Looks like they went back to the more human characters of the first game rather than the 2nd. I dont' see a Nopon in the trailer at all.
They also seem to be back to Mecho vs. Bion which is fine by me.
*this time I will stick with it! I won't buy it and then realize I don't love it. I will! Really
** I was a bit confused since this trailer says 7/29 but the announcement trailer said October - however the official Nintendo eshop page says 7/29 as well so 5 months earlier. Yay!
