I meant in the next year, but it's probably true of 2025 as well.
My primary basis is continually trying to get a Linux-capable machine with a RISC-V CPU, which remains difficult. Look at the number of SBCs released each year for the last... I dunno, 5-10y? A bit of x86, a lot of ARM, and at the very end a single digit number of RISC-V boards. Which still are slow, expensive, or both. Even if RISC-V ships exponentially more boards each year it won't break even until after 2025. If you wish to offer data to the contrary feel free.
Now, there's a possible argument for number of non-Linux-capable chips, but I don't know how to gauge that; the... Cortex-M0? I think? Is still a popular option AIUI. Likewise, if you have actual evidence feel free to share.
(None of this should be read as dislike for RISC-V; I want to use it, but the market doesn't yet agree, and even when it does take off the competition won't magically become "legacy" at a result.)
Edit: Actually that last bit deserves more emphasis - while I believe what I wrote about numbers, it's secondary to the rest of the comment; RISC-V is great, but it in no way renders everything else "legacy" so long as they remain actively used and developed (the latter is important, but ARM continues to improve so the point stands).
