School & independent teams have spent $$$ buying lego parts and it is still sad to see things deprecated when they could have easily upgraded the "cpu" and kept things compatible.
Spike Prime and 51515 (the final Mindstorms generation) seem to be basically the same thing (which isn't new, back in the NXT times you had NXT and NXT Education Edition).
I'd be very surprised if they weren't compatible with each other.
That page only mentions the long-discontinued NXT and EV3, not 51515 (the set that the article says is being discontinued now). 51515 wasn't compatible with NXT/EV3 either.
