The Arduino roadmap includes new boards with speciality functions, including GPS, ethernet, ZigBee wireless, and cellular wireless. The next generation of Arduino core boards will include Atmel's AtMega line with 64 I/O pins and 256k of memory. After that, the project will move to Atmel's 32-bit line of chips. People are considering implementing a proper debugger on the current Arduino platform, which would be great Arduino could be ported to the ARM chips pretty easily, although there are no plans to do so at the moment
I had a nice chat with a couple of people at FooCamp about improving the debugging side of arduino..personally I think we should use the popularity of arduino to push atmel to open the debugwire protocol that would allow the creation of a debugger inside arduino.
