IGN has posted another blog of Skate 2 called New Nug Alert!.

"Just as I thought I'd have to tap out on the whole new tid bits of info tip, it dawned on me that we may not have released any documentation of what our Trophies/Achievements are. This may very well be the last chunk of new info I have to offer...lest I explain the details of every challenge in the game...so, enjoy speculating on what these mean. Some are obvious, others not so."
