Not exactly easy to see (click on the picture for bigger one) but the NXT brick does boot v2.000 runtime, although it is not yet ready for prime time (pun unintended). We have supported AT91SAM7S256 chip for quite sometime, but v2.000 is the first release that allows full support for the NXT brick. We will be releasing complete project based on customized v2.000 runtime module plus code to support all the extra hardware like LCD, buttons etc.
