Sony learned from their Betamax loss
and bought a film studio.
Toshiba and Microsoft may regret not having invested in the content side of things before starting this phoney war, which I'm glad is now drawing to a conclusion. Only Paramount and Universal are left with any realistic support for HD DVD - every other major is now on board with Blu-Ray.
It will be interesting to see what announcements are made at CES next week - more pro Blu-Ray announcements is my expectation. And I very much doubt we'll be seeing the speculated "360 with built-in HD-DVD drive" announced - if it is announced I'll be forced to laugh at Microsoft in another of their Zune-moments. :)
Existing HD DVD owners will be looked after by Toshiba going forward. I'm pretty sure Toshiba will bundle legacy HD DVD support in their future Blu-Ray spinners in order to soften the blow of this eventual loss.
