Pete Sevcik from Techno-stuff was kind enough to send nxtasy.org some information regarding its support roadmap for the LEGO Mindstorms NXT.

The support rollout will occur in three phases:

The first phase is to test current RCX products with the Lego NXT conversion cable (W770323).

The second phase is to modify some of my existing RCX sensors for native attachment to NXT.

The third phase is to develop new products utilizing the enhanced features of NXT.

Phase one is nearly complete and many of my sensors are now supported for attachment to NXT. I am investigating an anomaly in the results of my musical pitch sensor. My current theory is the scaling algorithm that converts RAW into 0-100 is different in the default NXT. This is only a theory and is not proven yet.

Although the RCX has been replaced with a better product there are still a large number in the field. Techno-stuff will continue to release new products for the RCX as long as the market justifies it.

Be sure to check out all the cool Techno-stuff sensors that are now supported for attachment to the NXT. Techno-stuff now also carries the LEGO NXT/RCX conversion cable that can be purchased individually. Thanks for the info, Pete!
