Batman DC Nation Aardman Action Figure 5-Pack

Just saw these Batman DC Nation Aardman Action Figure 5-Pack up for pre-order at Entertainment Earth. I already have Batman & Robin. Doesn't look like there is much difference between these and the convention exclusive version. Definitely want the other 3 though. If anyone is interested, here's the link to pre-order the set of 5 for $67.99. Scheduled to arrive in September of this year.
