I highly doubt it, the device is over a year old and people were complain when the Icon was releases early this year that it had "last year" specs.
You have links to the 10/20 rumor?
I am with the other two I would look for maybe the 630 or something along that line. The 1020 is really nice. Personally I think it is better than the 1520 but I may not be looking at the same things you want. I have the 822 because it was a 1) good size for me, 2) it did all I wanted and more, 3) it was free. The last reason was really just icing on the cake. I looked at the 630, 1520, 1020, and a couple more at a local AT&T store recently and thought the 630 would fit me best. My kid wanted a 1020 or higher as they want a really good camera, which I don't care too much about.
Even with the latest updates on the cApple phone and my Nokia being a year behind it does not get me lost. I have had the cApple get me lost so many times it just isn't funny anymore! I told my wife to not use the cApple as a GPS as she was sure to get lost.
