Also, using the forum search I found
these two threads as well.
In sum, yes. It looks like there may be a new 7100 series (or 8000 series as someone else mentioned) that is in production this month (August). Hopefully that means that it will be available sometime this fall for Nextel (and hopefully Bell/Telus in Canada).
