Good point - I am getting really excited about some of the new players and ideas in the html5 video space. Just applied for the beta of http://sublimevideo.net/ - very promising, html5 video w/ flash fallback and mobile support.
Sublime is great, but closed-source and is going to charge for use. Many of the open source players beyond just VideoJS are just as good, IMO. Also depends on what you need.
