As far as I know any AVRISP MK2 (the USB version) will do PDI if loaded with the correct firmware.
The latest version of AVR-Studio - download from Atmel - will do this automatically when it detects an old version of software in the AVRISP.

Xmega is a very capable device with some nice features, but it has virtually nothing in common with the ordinary megas (apart from the assembler instruction set). All the hardware is entirely different- you can't "migrate" to it from ordinary megas, a complete rewrite would be needed.

They also have some nasty bugs which have never been fixed. Read the 
errata carefully.

Thanks for everyone's advice on xmega programming, particularly alerting me
to the bugs.  I checked them out and they either don't apply in my case or I
can easily work around them.  This is a new project so migration is not an
issue.   Also thanks for the leads on programmers.   Steve
