Will there be any or plan about the update of adding support for multi-device in ue4?

Waiting on an updated dll, but it should be in theory fairly straightforward to get basic support working after that. No specific timeline however, depends on how popular this feature request is.

I would LOVE to have this feature, it would be a huge benefit because in our use case that I use Leap in, sometimes the hand can get lost but having a device above and one mounted on a HMD would greatly help.

Feature will be tracked in this branch: https://github.com/leapmotion/LeapUnreal/tree/feat-multi-device

The https://github.com/leapmotion/LeapUnreal/tree/feat-multi-device branch is now in working state if you're brave enough to try. Documentation and a few stability fixes outstanding.
