Considering they haven't even finished the tpb's yet, I'd be surprised if they'd dip into a 4th format yet.

MTIO should be due time-wise to coincide with the FF Masterworks around that time I'd imagine.

Maybe Ghost Rider for an upcoming flick?

I'm sure there are lots of folks who'd love it if they pulled a surprise like Master of Kung Fu, but not likely due to those pesky liscensing problems.
