I'm personally wondering why anyone would chose to purchase a new receiver within the next year. Dolby Digital Plus and DTS-HD are not yet supported on any of the new announced receiver models from any manufacturer that I am aware of. I'm not sure if it will be possible to simply upgrade current receivers with a serial or USB connection to add DD-Plus and/or DTS-HD. If so, it's not so much of a big deal. But furthermore, DD-Plus and DTS-HD will require a connection with more bandwidth than either S/PDIF coax or TosLink optical offer...meaning either an iLink (FireWire) or HDMI connection will be needed. The new HDMI 1.2 spec is out now and really only adds SACD. Again, I don't know if current HDMI 1.1 devices can simply be upgraded. But it would seem clear that yet another revision to the HDMI spec is going to be necessary when DD-Plus and DTS-HD hit the market.
I personally think it best to wait at least a year for these features. Unless you have a lot of money and can afford to upgrade every year, I just see a waste of $1000+ in buying any receiver this year.
