And backwards compatibility was in the consoles it was advertised for, when backwards compatibility was removed so was the advertising. In fact the advertising had ended way before they removed PS2 backwards compatibility from the console. The only advertisement for SACD support was on the box itself, and it was only on boxes for units that had it. OtherOS was never advertised, it was talked about in some of the presentations, but never advertised. I even have a launch PS3 and OtherOS isn't even mentioned on the box. It is a bonus that they decided to remove, it was never an advertised feature.
