On the official WOTC forum Rob say:

“H.5 is a new starter.

You’ll want one for the updated rulebook, maybe the Korriban map (hooray, another map for organized play), and I think you can get two SWM H square base characters on round bases. And yes, I’m working on various aspects of J, K, L, and M at different times.

Noones mentioned N yet though, so I’m still able to cling to the remnants of my remaining sanity.
There are some other things in the works too, but I don’t know exactly what to call them yet.”
