Planned features include:
Hole cutting in terrain and
Terrain paging.

You know,RM series' default walk animation only has three frames.If you want to enhance,you have to code by yourself——especially majority of it's user are newbies.
Con No Hardware accelerate
You'll get a bad performance when you have big animations,especially in MV,which can easily change into higher resolution.
Con No 3D support
None of them have 3D support, it is possible only with manual scripting which could be difficult for beginners.
Con MV Does not have a "REAL" Android export.
MV has an export to HTML5 - which can run on any browser including android. It is however not a "native" app export.
Con Inconsistent included visual assets
Included visual assets within MV have inconsistent presentation. Though RPMMV does contain enough to make a small basic title, the visual assets don't often look like they should be mixed on-screen.
Con No built-in realtime battle system
RPG Maker series has only turn based battle systems, unless scripts/Plugins made by the community are used.
