I decided not to wait, and ordered a Panny P55ST50 from PaulsTV. $1149 including taxes (being in NY, AMZN would charge me sales tax even if they matched). Clicking through from ebates, I also got 2.5% which is more than the fat wallet 2%.
I am happy with a 55ST, even if the 55GT was only $100 more. 55" will be much larger than my previous 42" Panasonic, and PQ wise, the ST will be better than anything i have had previously.
