Pixel Pitch vs LED Lcd

Hi,

I currently have a VX1962wm with a 104.27 PPI, 0.2436mm(1680x1050@19''),I can get 4 years BestBuy warranty on it for 50$, 200$ for the LCD. The VLED221WM will cost me ~450$ with NO warranty.

I can still return my monitor but I am still lost because from one side 120Hz and 3D (VX2265wm) monitorz are coming out this year from ViewSonic but then will they have a good pixel pitch? From the other side therz LED LCD also, like the VLED221WM with a true 12000:1 contrast and a 118% NTSC colors but still it doesnt have the great pixel pitch as my screen. Is it worth waiting for the next year? Maybe a 19''@1680x1050 LED 120Hz 3D???

ThnX

Comon guys, I only have until tomorrow to return the monitor.
