Yes, I believe it;s better to wait. A lot of mods for UE are still working with PE, but with the risk, that they overwrite some new parts.
Look at @BuckeyeBoB's (BB) optional cloud mod f.e.: The cloud-variability is bigger and one of the best mods for UE in my eyes. But the sky-grafik in PE looks well, so I will fly without the mod the first days / weeks. And @BuckeyeBoB (BB) wrote, he want to release a new version (thread WOFF PLATINUM EDITION - EXPANSION RELEASED!, page 1).

I will test during the next days Nibbios InFlight-Map, News-Mod4.5 from 77Scout, historical Victory Information 1.3 from Aris, Realistic Tracers Effects MOD V1.2 from JJJ65.

At all other mods I wait for more Infos or updates.
