Does anyone with legal knowledge know how a class action suit would play out here?

I own a copy of CS5.5 that was purchased 5 months ago. I'm already frustrated at the cost of the CS6 upgrade. Now Adobe is publicizing a critical vulnerability in their software for which the solution is me paying them for that upgrade.

This feels a lot like extortion: "Sure would be a shame if someone followed our explicit directions and sent you a TIF file that took over your computer. Have you considered buying some protection?"

Does one need to wait for the threat to be carried out before one has a claim, or is the veiled threat itself illegal?
