I have no doubt ProtoMan will be playable. Remember, we've already seen the "default" ProtoMan look in the first trailer, so the recently released art looks to me like an upgrade armor along the same lines as the X, Zero, and Duo types we previously saw.
Iris, Command Mission cast, and Maoh the Giant are ALL in this game? This is ludicrous levels of awesome; we *MUST* pester the ever loving hell out of Capcom to release this game elsewhere.
The design doesn't wholly match Mega Scorpia, but it definitely heavily borrows from it. It's more like an "X-series" version of it.
I would safely call it Mega Scorpia. Nearly all of the characters in RMO, especially enemies, do not "wholly match" previous renditions.
I've noticed some other subtle Zero-series references. Ryusa Mixer and Rayblade, both from Z1.
