Jon,
Heres my take on this. We all know there are still various bugs even in 1.5.1 18 months is more than enough time to fix them and any other bugs that have crept up that hasnt hit the majority of users yet. Whats funny is the only bugs I ever discover are on projects that I have a deadline on. Go figure.
Furthermore, 18 monthsis more than enough time to invent some new features to catch up with the other NLEs and also match their features. While I want multicam in the worst way its more in that I refuse to pay $500 for the piece of crap United Media junk. I saw a demo hands on and it just sucked. The price is half of what my NLE cost so I expect Adobe to integrate it.
We all have heard time and again that Adobe provides a complete solution but how can that be when other NLEs can do more for around the same cost. With HD-DVD/Blu Ray right around the corner, one would think Adobe would start positioning themselves and their customers to prepare for the demand of it. Apple did so with FCP5 and DVDS4. So has Vegas albeit with a limited H.264 AVC codec. Avid has too.
While I am not a fan of frequent upgrades, Adobe leaves its users waiting for the upgrades but because that is usually the only time we get bug fixes and we have to pay for them. Look at the forum and look at the issues some people are having.
That are the reasons I love Vegas and Avid. There will always be bugs but at least those get fixed sooner rather than later and it doesnt cost me anything but bandwidth to fix the problems. With Adobe, the really dont seem to give a shit once they have your cash. They have always been that way.
Maybe its our fault for expecting more out of a company that we keep in business but 18 months is more than enough time to fix bugs and keep us on even playing fields with other NLEs so we dont have to go out and spend a fortune on crappy plugins that dont do the job very well.
