Compare 4:3 and 16:9 content in the box as an option.
I use that to try to figure out what to get to replace my 32" 4:3 CRT TV (yes it's a dinosaur - I'm waiting for black friday). Oh and the answer is 40" 16:9 will replace a 32" 4:3 TV for viewing 4:3 content sometimes.
Not sure that's worth it. Black Friday is increasingly becoming a gimmick, more lottery than deal, and on the other side, if you're not too worried about exactly what you end up with there's pretty much continuous deals on all the major retailers for deep discounts on one model or another of TV. I doubt you're going to be able to do much better on Black Friday that just cruising Amazon's site for the next couple of weeks and waiting for a good deal to pop up.
At the risk of going (further?) OT, the new black-friday is the "PRE-black-friday" sales in early November where they try to get you to spend money before the supposed sales later in the month. I actually got some unprecedented prices early last November.
Agreed on this one... just before BF, I haggled with the local appliance places showing them some online offers and ask them to match (equating for taxes and shipping).
