Just read this article and take a collective "what the fark are they thinking?". This isnt 100% related to PS3 but with how Blu-Ray involved in this horrible way of alienating people and PS3 using Blu-Ray, I think this will be a very bad decision by Sony if they make it so only people with HDTV's with an HDMI or DVI connection can watch next-gen movies and quite possilby even games if this is how it pans out.
