Yeah, there's a lot of conversations on when or if they'll come up with an update. Most people that have contacted them (from what I've heard) haven't heard anything back.
When I bought my chip about a year ago, it was said you could update with the JTag, BUT you could also update from disk. Ya just burn update to disk, put in drive, and your done.That's really the only reason I bought the chip to being with.
Make sure you cross ur fingers like the rest of us in regards to an update sooner than later!
