Well if MS had actually created a competing product many years ago no one would even know what flash is. I hope CS4 will have it as well, don't want to upgrade.
Anyone that thinks us CS4 users are gonna get a free upgrade to have this ability is smoking the good stuff. There's no way they would do this, and it completely goes against their entire business model that they've used for CS software for as long as I can remember. They've got to come up with something in every release to appeal to someone.
