over in various threds in Uverseusers that people are testing 2 HD steams right now, its not an additional stream so its 2 HD/ 2 SD and there are some that say they are testing WHDVR too.
In my opionion, 2 is not enough. Sure, right now most households now only have one or two HDTV's in them, but pretty soon 90% of TV's sold will be HDTV, and even the small 24 inch flatscreen TV you bought for your daughter is going to be HDTV.
Add to that the explosion of HDTV channels, and I foresee a future within the next 5 years where having three TV's on different HD channels on in the same house plus a fourth HDTV stream going to the DVR to record stuff.
If they are having difficulty now to do 2 HD streams, copper is surely not going to be able to deliver 3 or 4 HD channels at the same time.
Edit: I should say telecom copper, as cable tv copper has no problems with more HD streams.
