Having a busy day, Nokia Beta Labs has formally launched a next-gen Java Runtime for S60 5th Edition and upwards - presumably this will make it into future device firmwares. In addition, version 2.0 is a component which can be maintained in the future independently, through the 'Sw update' system built into each device. The technicalities of the update mean that the installer (a 4MB SIS) includes a routine to modify any already-installed Java MIDlets to work properly with the new runtime. More details below.
