Don't know about the 2011, but I hearda lot about the glare and washed out nature if the pou50. As a first time flat screen owner, I find these concerns overblown and geek-tech oriented. If you have bright lights facing the tv, of cours you will se reflections; however, I thnk the picture is stunning, the different viewing modes compensates (custom, cinema, vivid, etc,) and the colors are stunning. Highly recommend.
Grain/noise is native to plasmas, Panasonics especially it seems. I changed my tv and blu ray player setting to 24p for watching blu rays and like the improved picture. Give it a try and see how you like it.
