People there is a concern in the market regarding the availability of HD discs, the only thing we can do is to wait for the market to open up,upscaling gives u a slightly better quality than others,Blu ray players wont play all the regions,and more over the choice of the films is limited and for sure you wont find what u are looking for, analyzing everything Ps3 seems to be a better buy to enjoys games and Blu ray movies.
I also heard there are Hd receivers available dont know exactly whats their result.
