I know it’s an old thread, but thought I’d comment:
The g2 board does have heated bed support- always has, actually. The deal is if you use the cloud, it is not included. The cloud is for pla primarily. Although that feature should be available soon.
Anyway, the g2 board understands regular gcode so you can slice in cura, slicer, whatever and print w cura and repetier... printrun... octoprint but not simplify3d (complify3d

It’s faster, quieter, 32 but arm. But you will need to set up your machine w a starting gcode to run it. It’s a one and done deal.
