I must add my words of support here.
The TW2.0 programmers are to be cogratulated for listening to their clients and the fine work they are doing. As far as the pricing goes, programs like Photoshop are able to have lower prices due to the economy of scale. There are not nearly as many TW users as there are Photoshop users and nor would we want there to be or we would all be out of business. The progrmmers and others at Easypano are part of your production team if you are using this product commercially and they need to be paid as well if they are to continue to do the great work they are doing.
I am ready to pay the $200 for the upgrade once a few fixes have been made. There are many improvements including the great GUI, full screen view, file compression, smooth panning, user preferences, improved timeline editing functionality, movie control, WSYIWYG editing screen, colour sampler, and many more including some which I probably have not yet noticed.
