I don't know how to say this, it truly does saddens me greatly, but it needs to be said - this franchise is over, and its permanent.
They don't have the talent needed to reboot the series, and to keep on churning these outdated relics, well, that's just a waste of development time. Its pretty clear to me that if you look at the retention and popularity of the series, there is nothing left. Insane hype for the series back in the day, and look at it now, its a completely forgotten IP. Very sad.
