They sell a few thousand Elites per quarter. They would move somewhere between 3 and 10x as many 945s. This isn't about protecting the Elite. They can easily do that with a few features and some cosmetics.
They would capture tens of millions (minimum) in additional gross margin by having the 945 in the product line (I did an analysis on this last year, someone bored might try to find it although it was based on something called the 935, last year's hypothetical version of this).
There is something more going on here. As I said in the other thread, I have ideas as to what, but they involve speculation that isn't especially interesting at this point. You can look at production issues, channel issues, perceived value of the Sharp brand to consumers, etc. for ideas and form your own guesses.
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.
