It actually falls in line with what Yoshi said. Increase of level would happen before the expansion, and in so doing would also include new classes. Classes like the musketeer. Yoshi also said he wanted a stealth class.

This is very much in line in what I have read.
-Higher level cap before 3.0.
-New classes before 3.0
-Gun and dagger classes that Yoshi has talked about a few times.

But my speculation is if there is a Gun class it will be Red Mage. Yoshi basically said one of the first jobs to be added would be Red Mage.
