No. Epic confirmed that blueprints aren’t going anywhere. There’s no problem with it and it’s priceless for everyone.
In comparison to the clunky pair of UnrealScript and Kismet. None of these tools were flexible enough.
They made billions on 3D mobile games. Still supporting them, of course.
This is where Nanite and Lumes might be useless for now, so this a reason to keep old pipelines in the engine. Especially that this weaker hardware also is getting upgrades.
One thing Epic simplified (on the rendering side) was the removal of HTML5 support which required to support the ancient version of OpenGL. Not it’s gone, mobile platforms getting upgraded to be closer to desktop renderers. That’s already happening, look at the last UE 4 releases. There’s no reason to upgrade all the platforms and then abandon it. That would make zero sense and would have to be announced a long time before dropping UE5 Preview
Again, you assume that Epic is a bunch of amateurs that would remove such fundamental parts of the engine like blueprints or support for platforms older than PS5… just like that, not telling anyone. Just basically removing half of its technology for no good reason.
