So, Adobe has announced that they will be making Flex 2 available free. A lot of this probably has to do with the fact that Laszlo has been free for quite some time now: http://www.andersblog.com/archives/2006/01/free_flex_frame.html
It doesn't include the Flex Builder IDE (that should be somewhere under $1000) or the Enterprise Flex Server (you can use low level MSDE like version for free), but the decision to offer the framework at no cost is significant nonetheless. This means that the door is open for both 3rd party SWF generation tools to make use for the Flex framework and 3rd party server products to take the place of the Flex server. Keep an eye out, because I'm sure there are going to be some people that are smart enough to take advantage of this.
