The problem is that people are being careless and jumping the gun, I guarantee that's why most of the bricks have happened. Looking at the results spreadsheet, there's an extremely high success rate on both old and new models (remember that there's always a vocal minority, in this case the bricks). Myself and several friends have made it to 9.2 just fine, but again we triple-checked EVERYTHING before proceeding.
Use a clean formatted SD, verify your ZIP type and MD5, and use one of the "safer" builds (we all used Julian's, despite it taking 100+ attempts to boot for a couple folks) and you should be fine. People are overreacting as a result of other people being careless. Is anything guaranteed? No, of course not, but this is much less of a dice roll than people are playing it out as.
