I have been asked by a couple of people why there is only the TrueNorth PHP logo and not the standard PHP logo, as there are on the predecessor elePHPants.
I can understand, especially for a collector why they might want it to be consistent. The simple explanation is that it will cost an extra $1500 to put a second logo onto the plush toy. This project is already quite expensive and we did not want to have to make the funding goal higher. If we exceed our funding goal by enough, I may put it to a vote and if enough backers really want the extra logo I will see about putting it on.
