as better filter design and antenna systems come out the edge power will go up, but it will be some time before the market forces the costs down. hopefully enough pailure in band edges and congestion in center channels will take place that consumer demand forces the shift. The hump in the middle is going to suck though, and its unlikely current systems with the limited band edge output will be compatible, lots of stuff on ebay in the near future
