The construction is significant, but the November 2013 launch date seems to be based on someone raising more capital.
http://www.jasmine-galaxy.org/nano/nano-en.htmlNano-JASMINE is the technical demonstrator of JASMINE mission, and also the first space astrometry satellite mission in JAPAN. It will be launched at Aug. 2011 from Alcantara Launch Center at Brazil by Cyclon-4 rocket.
Yep, the article says that they are underwater financially.
The current Cyclone-4 capability can be augmented with SRBs to provide a much larger payload, per the user guide.
Also, the current price of Dnepr is rumored to be around $24 million for LEO payloads, so Cyclone-4 should be competitive for some LEO payloads. Of course, there continues the problem that Brazil never signed the MTCR, so US payloads may never fly on Cyclone-4.
Are you reading the v02 document? I did find that a 2tonnes to GTO version "is in development".
