Do we know when the next version of the IDE will be out and do we know if there is going to be support for more ATmel chips like the 664 and 1284 ?
I'm of the opinion that the official Arduino IDE will never ship with built-in support for processors other then those processors that are used in boards that the Arduino firm sells. The sanguino and it's modified 'core files' came out around verison 11 of the IDE and has yet to be included as of version 22.
They have however placed 'hooks' so that 3rd parties can put 'custom' core files into a folder named hardware in the users sketch folder (same method that allows user contributive libraries to be found if put into a libraries folder) so that when compilying a sketch the IDE will replace the normal core files with the 'custom' core files. That would still leave popular contributive library files possibly needing updating to support non-standard arduino processor types.
All in all, it's a bigger job then one might think when wishing to make the arduino platform fully support non-standard arduino AVR chips. A lot also depends on what arduino functions one wants or needs to use in their sketches.
