As a side note, I think the icons are pointless - too tiny and busy to actually see anything. Plus, they disrupt the overall statblock layout. Hopefully, there's enough time to actually change them before print.
I have to agree with you here. They are small, redundant, and make the monster entries look very busy/cluttered. Now I have to flip back to a table at the beginning to understand what the symbol means. To me that's bad user interface design and quite possibly done just to emulate Wizards use of symbols in everything in 4E. I don't care for them and would not be disappointed in the least if they did not make it into the final Bestiary. They remind me of Mana symbols in M:tG, and the last thing I want to think of when playing an RPG is a CCG. Maybe its just me though.
