We've played with AWIPS II here at OUN a little bit, so I can provide a
little more insight...
It is written almost completely in Java, under the Eclipse IDE with SWT
widgets.
It makes heavy use of Open Source projects to provide a Service
Oriented Architecture (SOA) using XML messaging. Just about the only
"closed", compiled code in AWIPS II will be some of the meteorological
calculations that were originally written in Fortran for maximum
performance. This code will remain, with APIs to the AWIPS II Java
code.
Data will be stored in HDF5 with metadata in a Postgres database.
It will be GIS-aware, likely via Geotools.
I believe the code makes heavy use of OpenGL to offload many operations
to the graphics card. There is also supposed to be a "thin client" to
run on less capable hardware.
Much of the local development will be done in _javascript_. Raytheon
will be writing _javascript_ function libraries to hook in to all of the
underlying functions for data access and rendering.
That's about all I can think of off the top of my head.

AWIPS2 is supposed to undergo operational testing and evaluation at a
few select NWS forecast offices starting in the summer of 2009. I have
not seen any examples of AWIPS2 other than what I read. It is being
written in Java, and will be heavily GIS based. Instead of having 5
fixed scales like AWIPS, AWIPS2 is supposed to automatically adjust the
scale and resolution of the displayed data depending on how far you
zoom-in on an image. (Similar to Google Earth?) I look forward to
seeing examples and maybe a demonstration of how it will work.
