I've been creating tools for ArcMap using Delphi through COM even though it isn't officially supported and I'd like to know if that will still be possible with ArcGIS Pro?

No. ArcObjects will not be the development model for ArcGIS Pro. Your two development options in ArcGIS Pro are either via a new set of .Net APIs or via Python.

  • Apart from GP script tool, I've heard that Python add-ins are supported as well, so one more option for GUI customization. Dec 3, 2014 at 6:57
  • No, there are no Python Add-Ins for Pro. Dec 3, 2014 at 8:56
