I don't know for sure. I haven't heard anything directly answering that yet. It's just a guess from me. I believe that if-when WoTC undertakes to do that, they would Release each updated module one-by-one, and would advertise and make a somewhat big deal about each release. They might call them "Modules Remastered for 2024" or something like that. Since there hasn't been a single one yet, that I know of.. perhaps it will be Phandelvar first? So unless they do a huge batch and re-release all the 2014 modules updated for 2024 at once (which I don't envision that happening)... it would probably be a long time down-the-road before eventually Witchlight is ever done. After WoTC does it officially, then Roll20 can implement it here. I think it will happen over a long process, many months if not years. It's a good question to see if you can get an official answer..
