Earlier this week, the
Financial Times ran their report that Paramount was "poised to drop its support of HD-DVD" after Warner Brothers bailed on the format and went Blu-Ray.
It's said Paramount has denied this immediate move, but they may simply not want the story to get ahead of them since the news from Warners caught everyone (especially Toshiba) by surprise right before CES.
Para's HD-exclusivity deal seems to have an escape clause if Warners backed Blu-Ray. Speculation exists that DreamWorks (i.e. Spielberg) might well have the same exit clause since their contracts were completed at the same time, and they have close distribution ties to Paramount.
If Paramount goes Blu, so will DreamWorks, and that leaves Universal holding the HD bag which should end the format war.
My guess is that if Paramount is even planning to drop HD-DVD, they won't bother producing the Indy series in that format at all ? only on Blu-Ray and standard DVDs. Watch the headlines, we might know soon.
As for Spielberg preferring one format over the other, I haven't heard of proof. Only one of this films have even been released in hi-def format so far (CE3K), and that was Blu-Ray only because Sony owns Columbia. Not really much choice for Steven on that one.
