Have so far been trying to manage without an external monitor or any kind of zfinder device..

Recently saw this Twitpic - Share photos on Twitter (http://twitpic.com/1i35mm) and was wondering if anybody knows of or thinks there may be in the future some kind of hot shoe mounted swivelable viewfinder coming like this that would i guess plug into the HDMI out?

This would be a great option!

This rig wil allow you to use a proffessional videocamera viewfinder. (pdf) http://www.kinomatik.com/produkte/mt_pr/MOVIEtube_PR.pdf
