For me, the definition of RVA23 and Ubuntus declaration to only support RVA23 starting from Ubuntu 25.10 tells me that RVA23 is the future and therefore is my personal Osborne effect.
Currently I don’t see good reasons to order another SBC from any vendor just to play around with the ecosystem, if it doesn’t support RVA23. I use Debian and not Ubuntu, but I believe RVA23 will bring major improvements in terms of speed and general usability (GPU drivers remain a problem).
But I understand that they probably don’t want to risk sharp decline in sales if they announce a successor.
