HVD! no f-ing way, a HVD player today cost $15,000! and 1 disk cost about $150! even if the PS4 will only be released 2011-2013 its still going to be expensive as hell, and I don't think Sony can pull another PS3. Like I said many times it'll pretty much be a PS3.5 instead of 4, and definitely not QF-HDTV maybe PS5. Where do these people think Sony's getting all this money from?
Either out of their ass or sales they are making from the PS3 right now / since launch.
OT: This has been shown before. I've seen it on here, I believe. The chart is laughable, because with the way the economy has been, I very doubt anyone would want to spend their hard-earned money on a luxury item, especially technology when it can become redundant (HD-DVD) or improves within time.
