They predicted two areas that encryption would come under attack, and then followed up with two examples where snooping only happened because encryption wasn't being used. Seems like a bad call.
"Attacks on Lack of Cryptography"?
They give themselves too much credit for the SSL prediction. Firesheep wasn't a new attack on an SSL, it was an old one in a package so convenient that everyone finally paid attention. For a moment.
As for GSM, yeah, that's just the old "computers will keep getting cheaper and more powerful" prediction, dressed up.
They didn't exactly go out on a limb with their predictions - they said that GSM security technology and SSL implementations are flawed, so we'll see more attacks on them in 2010. Anyone who follows security and/or web technologies could have said that.
