Should I stick with last year's Sony 60" we610 model or go with the newer WF655 for $520 more? Anyone had the chance to really look at the new WF655 series? I know it has the HD reciever, cable card and allthat built in, but as far as picture qaulity alone, is there a visible improvement? Specifically pixelation, screen door effect, and black level. I jsut can't tell....I've only seen the XS model and can't fine the 60" WF at CC, BB or anywhere.

Thanks
