It's only speculation on my part, but Temp-tations hasn't had a TSV in several years now, and their full hour shows most often take place in the middle of the night.
They used to be on a cooking show with at least one set/piece about every week, and that doesn't happen anymore either.
It does seem they have saturated the market. Quality is better lately than it was a few years ago, but it may be too late to really save the brand.
It could be that Q is baking down a bit, and will have a resurgence of the products at some time in the future, and only time will tell, but it wouldn't surprise me if the brand is under contract for a period of time, but will be phased out eventually.
