In my case the camcorder is just in the dry cabinet...
It was bought in the 90's and resolution is only 480... (it was great in the 90's but now almost useless)
Nowadays, I use my Mirrorless Cam for my daughter's school events. (let's face it... Last person I saw using a camcorder was
Zaza Pachulia 
)
You're right in waiting for 4K camcorders to go mainstream...
IMO, 4K makes your videos a bit future proof...
Sony and Panasonic targets 8K for the Tokyo Olympics... Once 8K TVs are released, our HD Videos might start to look bad...
