I can understand the need for a break. We all reach a burnout point, but a lack of interest. I don't think so. As in real life the ETO got all the glory and the MTO and PTO not to mention CBI got the table scraps.
One need only look at this forum to see an interest in MAW and this is an area that has only had its early years/months covered. I for one was looking forward to the missions that covered Operation Torch, and Tunisia as well as Sicily and Salerno. So much will be missed.
As for PTO, remember that CFS2 was a PTO only simulator and if you check that forum you'll see that it's going strong today. Here again it is more a lack of material, which must I admit, has to be made from scratch, than a lack of interest. This is an area that has so much room for creating missions and aircraft. The island hopping up the Solomons and New Guinea with the US Army Air Corp, RAAF, RNZAF and US Navy carrier ops. Lae, The Battle of the Bismark Sea (a real shoot em up), and the campaign for Rabaul. There is a lot of creative gold to be mined here. I'm not very familiar with mission builder myself, but I have a couple of ideas for historical Wildcat missions floating around in my head I might try.
So, by all means please take a much deserved break and rest we all need them, but a lack of interest? Never!
