I see they've taken Dungeonpunk to new heights with the spiked armor having additional spikes and upon those spikes hang not only an asssortment of critter hands and heads but bags of coins, spell componants, magic items. They even have a spike of holding that doubles as a critter part holder for when you just need that one special body part to adorn your newly aquired spikes.
The DMs guide now has tables with not only standard wealth for PC but standard spikes, buckles, tattoos and body piercings. I have already heard whispers amongst players planning rebelling against old school DMs who don't use these tables. The players say that even CR is adversely affected if these tables are followed to the letter.
Also I saw some new feats, they are really cool:
Improved double-spiked armor
Grow body spikes (you never want to be without the necessary spikeyness)
Eye regrowth (for one you lose an eye on a spike)
Undo buckles (buckels came into style in a big way in 3e especially for sorcerers)
Improved undo buckles (this trend continues in 4e)
Superhero pose
Improved super hero pose
Subdue enemy laughter (for when the BBEG thinks you look too stupid to fight).
Best of all was the new epic feat:
Dragonball Z - This feat allows the character to stack all feats and magical enahancements from all sources at all times, to fly at 500', and to shoot bolts of pure munchkin energy out of his clenched fists utterly destroying any mortal or petty godling beneath DivR 21 or anyone who is not Orcus, Asmodeus or the Lady of Pain because as everyone knows these three are the coolest cosmic overpowers ever.
Another noteworthy development is the Core Rules DM Domination Plug. This little plug attaches to the back of the dungeon master's head. Should the DM for any reason create a house rule, veto a core class, PrC, feat, etc. from a WoTC book or do anything that for any reason leads a player to believe his character was "nerfed" a powerful charge is sent into the DM's brain effectively over-riding the DM and forcing him to use RAW and fully empower the players to make any choice ok'ed by WoTC.
