Same thoughts over here.
Solution #1:
Get a Loewe with dolby digital/dts module (pre-amp out) use tv speakers as center speakers, use line-in of your beolabs. Beosound 3000: only via Aux-out attached to the loewe TV.
Remotes: Beo 4, Loewe (if you take the assist multi control you can at least use it for your sat-box and dvd/blueray player)
Solution #2:
Get a Pre-amplifier (for example Denon 2809, Harmann Kardon AVR 355) and attach your Beolabs via pre-out (using cinch/rca cables).
Aux-out for Beosound.
Screen: LCD or whatever. For most of those you cannot use the TV speaker as center.
Best would be (also better for solution #1) to get Beolabs as center speakers as well.
I have not yet decided which way to go, but I will wait another 6 months (LED backlight has just made some major steps, see several tests of Samsung, Sony and Philips screens).
