I am dying to upgrade my TV as I only have a 32' Sony Wega at the moment

BUT all the Plasmas I have seen look pretty pony picture quality and I have heard loads of stories about the picture quality of normal TV's being better?!?!
Is LCD going to be the way forward for the next 5 years or is there something even better on the horizon? I want at least a 42' screen but I don't want poo quality!
