Japanese and European Blu-Ray Discs in DTS

[Jodi]

Can some of you please tell me what Blu-Ray discs from both Europe and Japan have, at least, English DTS 5.1?
I won't have any problem playing back Japanese imported (Region A) Blu discs on any of my Blu drives both present and future (I currently own a U.S. PS3 and WILL purchase Sony's BDP-S300 in November or December).
As for Euro Blu discs, Pioneer Elite is about to release two new Blu players here in the U.S. that will play Blu discs from Europe (which, of course, will require a PAL monitor or projector). But I won't be getting the Pio's. Hopefully Arcam will eventually go Blu (as their standard DVD players DO convert PAL to NTSC), but I don't see that happening for at least two years.

Thanks,
Jodi
