What is this about everything is core?
Basically, 5 years ago some of the 4e developers stated that in 4e, everything will be core. One of the first examples of this was the Swordmage class, which appeared in the FR Player's Guide. Despite the fact that it appeared in a campaign setting book, it still received support (new powers) in generic supplements such as Arcane Power. In the end, it didn't really amount to much more than a marketing gimmick, but as you can see there are still a lot of people offended by it.
Here are a few threads on the subject that are more chronologically relevant:
