That's a great question; one that a lot of us are thinking about.
The 998 was announced on 3/12, just about six months ago. At the time, it was stated that it would be available before the end of the year. We haven't heard much since then.
One encouraging sign, is that they had asked for special beta testers a couple of months ago. While it wasn't explicitly stated that it was for the 998, the description in the email seemed to fit. If that's the case, we could be on track to see it by the end of the year, as long as testing goes well.
Where does that leave us? Beats me. It would be nice to get some kind of an update. All we seem to be hearing about are new processors/receivers from other manufacturers. I'd rather hear what Outlaw is going to be offering themselves.
