. It is already makes 204,8 GB/s bandwith with 256bit bus and 1600Mhz GDDR5. That is pretty awesome, isn't it

By "nobody" you must be referring to the consumers, because the manufacturers don't care how much it costs, as long as it translates in profit (the HD 5970s go up to $1.2k, so m'eh).
And every generation of graphic cards improve on one aspect or another, but mainly to increase the total performance, compared to a previous gen. So to answer your questions, yes it is pretty awesome and NEEDZ MOAR!!
