We will keep the original version around for as long as it takes us to make the new version something that people like. Maybe we'll leave it forever... really depends on the usage of the new section and how good we can really make it.
Starting on March 1st, we're going to be implementing a new frequency capping system, which should make it so that you only see one ad every 5-10 minutes or so. That way, if you're watching a bunch of shorter vids you won't be assaulted.
Also, we're going to change the layout of the video view page so the player is much bigger, we can go to widescreen, and the comments will be much closer to the video in question.
After we've dialed in that page, we'll work on the gallery listing page. I'm sure there is a happy medium we can come to that will please everyone.
The one thing that will go away is the ability to embed foreign video sites. No more vimeo/youtube/etc. You can still add those to blog posts, profile, etc, but just not into our video section. This was a hard decision, but we must take it for the sake of our business. We won't do this until our video system is good enough, but it would help if you guys use at least the video uploader to give us feedback.
So again, we'll keep the old system around as long as we need to... which possibly could be forever but we'd prefer to fix the new one so that we only have one set of pages to maintain.
