Yes, but they already have most of the 2024 SRD already written. The changes to the axtual core rules per the latest UA playtests are about 5 pages. Given the importance of the SRD to free on ramping to Beyond, that will be a priority this time.
I hope you're right, but I'm skeptical. I can see DNDBeyond getting a free basic rules source that isn't actually an SRD in Creative Commons.
