how out of date am I?

At that date I think you are looking at the 5th Ed book. If it doesn't have Pegasus Knights in it, there is a later book available. However I wouldn't buy a new brand new copy, as I expect a new version in under 12 months. eBay would be advisable, but I have a copy somewhere you can look borrow. Somewhere big tidy up last weekend, and a few books including one I want to read, are hiding ATM.
