The pricing strategy is one adopted from Bose, Apple, et al. It generally is immune to sales, with relatively minor discounting and special promotion. (For example, Bose will throw in a free battery with the headphones around Christmas... Apple will take off $100 on a Mac laptop on Black Friday.)
I'm not actually saying this will work in the marketplace or that they'll stick with it, but the strategy is clear:
You will pay MSRP and there will not be discounting of any meaningful kind. Even if they do things like bundling, that's (a) noise in terms of discount and (b) irrelevant to those of us who have things like BluRay players, sound systems, etc. already.
We are talking de facto price increases of upwards of $1000. I personally believe this is insane but that they are committed to trying it. One thing that might have made more sense is splitting the difference between the old MSRPs and the current street pricing. That would've worked out for retailers still (no competing with cheapie internet dealers) and would've kept their products at / near the competition. The notion that people will just happily pay more for Samsung products in a world where other products -- including for what it's worth cheaper Sonys -- exist is really bizarre.
There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working.
