Idk, VLC is kinda everywhere and while not the super cutting edge of video playing anymore, is still pretty OK. If they'd just attach a chat and SIP client to VLC they'd be set.

I don't know what's the ETA on VLC 4 but it's been entirely usable for me for the past year, and it's pretty cutting edge (internally). Hopefully it's not too long before we'll see beta releases.
