I have 5 divisions I can task for something, and I had been generally planning for a Ceylon offensive prior the unpleasantness in Burma -- now not so sure. A major push in Burma is possible or simply defensive posturing and preparation.
Since it is now '43, I would go with where they can protect your economic assets. Ceylon doesn't help at this point, IMO. Thinking along this line I would go with Burma and/or northern Australia to protect the vital oil in the SRA.
I pull out of active duty my APs that can convert to APAs in 3/43 as soon as they get to USA in early '42. Thus, in April the Allies will have some assault shipping to use and the Hellcats will start to become a nuisance.
