I am sorry my friend, I did not make clear my statement. What is not proven and is new technology is Immersion says they can make rumble work with new PS3 motion sense controller. I do not know if even they have made lab model (even many developers did not know of new controller type) and then in < six months they must make mass production model.
What is arrogance about this statements? First statement by Kutaragi is maybe true or maybe not true (who can be sure what date RSX is taped out) but many times companies say things like this for investors to have confidence during restructuring and even on normal days. It is very normal in business world.
Second statement is true. PS3 price is too cheap like Xbox360 price. Market price for small quantity (only 2 Million international available christmas season units) new release console is closer to $1000 than $300. Also, because of Blu-ray and "heavy" prerelease advertising of this feature, who can know what is the extra price people will be happy to pay? HDTV customers will be happy to pay too much for anything HD, especially in Christmas season, and even have very large debt to buy such toys to show off to neighbors, friends and office people, and sometimes maybe even for competition with other sibling.
