If not, there better just not be a Kamek counterpart in PM style. If there is one, Kammy is the only one I'd want. Paper Kamek was nothing but a retcon of the more original counterpart set up by the first Paper Mario.I'd love to see Kammy come back, and then interact with Kamek (namely, bicker like an old married couple - it'd be funny, imo), but it probably won't happen, sadly.
Best case scenario, we see the return of multiple villains and allies from both series. Worst case scenario, Starlow becomes a beta element and the game is crammed to death with 3D Land and NSMB crap.
