You could just stop at "I haven't noticed". The second rise would probably be more like 2-3 years out tops (which is also nicely consistent with the time frame for when they want you to throw out your old tv and buy a new one), not 10 years. Next, it would make them more expensive???????? WHAT??????? Panasonic already charges more for a comparable product than either LG or Samsung, both of which don't exhibit rising black levels, floating blacks or any changes in PQ.
