Well obviously big software houses have had exclusive access to use UE5 before anyone else…
I hope 99% if not 100% of assets bought on the marketplace for UE4 will be fully usable with UE5 without requiring a massive update to change everything which most sellers might not do.
And… is UE5 going to be more modular source code wise so that bugs could be addressed quickly and not become a huge issue like it is on UE4 between releases for poor indie developers at least ?
