UE4 mobile is designed for handhelds.
Yes, it's not a sure thing that UE4 won't be available on the handheld. My not-that-great $150 tablet can run UE4 full speed. It's all about how well you optimize each specific game for the hardware. UE4 is very scalable.
If it doesn't end up on the handheld it'll be due to a business decision, just like with Wii U. Not because the hardware couldn't handle it.
