That is exactly why they bought DI - for the older educational market. The Raspberry Pi is still very strong value for the price, and the micro-bit even more so for the intermediate grades.
The educational robot, and more general STEM (Science, Tech, Engineering, Math), market is growing really fast, with a lot of competitors and venture capital.
MR+DI pulls together broad coverage, experience, and potential, so the future of an inexpensive capable Raspberry Pi processor, Raspbian/Linux OS, with a programmable microcontroller physical robot layer, supporting lots of 3rd party sensors, that comes in somewhat easy-to-assemble kit form should continue to meet the higher grades’ needs. (It’s not cute though, and it’s not new - both of which may be important for strong success. I don’t know how to judge that.)
History would suggest that it is very, very hard to be successful long term selling robots, but many organizations have “made it” selling education. Hopefully, the GoPiGo will get taken along for a success story.
