Ben,

: Dolby and THX annouced a new surround format again. It's 6.1 Dolby Digital EX.

They announced EX some time ago. Dolby Digital Surround EX is not a 6.1 system, it doesn't have seven discrete channels, it is a 3/3:2.01 system, with Centre Surround being matrix encoded into Surround Left and Surround Right.

: But will it become a new format (again) for LD or DVD eventually ?

No, not exactly because it's simply Dolby Digital delivering additional information which is fully backwards compatible. All that will be required is a suitable decoder, probably a THX design to extract the additional channel.

: I'm building a new home theater, so I would like to know if I have to installed the center rear channel for future use with this new format.

Yes, if I were you I'd put a Centre Surround loudspeaker in place. If you have a choice, install a bi-pole which will provide the best of both worlds both in terms of directly radiated sound and a slight diffusion.

Stuart.
