And? Any reason that should mean Paramount and Universal would want to jump in sooner rather than later other than for considerations?
If Universal and Paramount are not vested in the disc-based hidef movie market, they wouldn't participate in HD DVD or Blu-ray in the first place.
Beyond the format war, it is a great thing for the studios have an additional viable market. So they would certainly appreciate Blu-ray's success. At the end of the day, I have my own assessments but you clearly have your own opinion too.
Just another reason for them to let the others test the waters. Why should you waste time experimenting when you can let others figure out what works?
Because the BD-Live extensions leverage or express individual studios' strengths and desires. It may not be something portable across studios. e.g., Fox experimented with MySpace because it is also owned by News Corp; the AVP online game may indicate their interest in the gaming space. It is about finding additional revenue sources for the company... or even license stuff out to other Blu-ray companies.
You're just not understanding opportunity costs.
If you say so...
