The 9500i finally got it's FCC Equipment Authorization Grant today.
Strange that it took so long. Unfortunately, the "short-term confidentiality" exhibits are still not viewable, even though they are supposed to be viewable to the public once the product hits the market. Perhaps we'll see them in the next few days.
As long as they follow the same number convention, we can already assume that it has an "M4" style receiver like the current X50 and RX-65. I won't expect anyone to have the balls to actually take theirs apart for a while.
