"Poltergeist 4" Coming?

So it looks like MGM have finally realized that reboots are everywhere and that they don't really wanna join the reboot wagon. They've decided to do a direct sequel to the third film. FANTASTIC! It's to be a bit different from the original franchise, but not in reboot style, in sequelizing style. They're just changing it a bit for the "now generation".
I wonder if the new "ROBOCOP" film will still be a reboot or just a plain old sequel to "ROBOCOP 3"?
