only preorder bonus i've come across is from GS, but tbh having a cache of wpns at the start of the game that you're automatically proficient in seems to dimish the experience slightly...at least for the purist, but i digress. 87 bazilion possible wpn drops, it shouldn't worry about the bonus. Though you could just sell them and say you started with more money.
yeah, im looking for a better preorder bonus but i think due to the games mature theme it probably won't get any outstanding preorder bonuses in any main stream dept store.
I'm definitely in for one, but with all the crazy B2G1 deals, I think I can wait til the price drops or for black friday sales.
