After a routine visit to the N-Gauge Information Blog, I've noticed this announcement: http://ngi.blog.eonet.jp/n_gauge/2011/07/greenmax1000-8c79.html SO MUCH AWESOME!
It's concerning an unpowered model of the Haneda Airport - Hamamatsuchô monorail of the 1000 Type by Fujimi (unpainted kit) and Greenmax (prepainted kit) and is sold as a 'Structure Kit'. Yes, this would be a joint-venture project from the two firms.
Now, I'm sure someone will play ball after the release of this kit and develop a battery powered set or maybe a develop some sort of system, making it able to run on Z-gauge tracks or whatever.
Here's the official poster: http://greenmax.co.jp/image/new_release/tokyomonore-ru-1000_poster01.jpg and the official release message: http://greenmax.co.jp/Schedule/GMschedule02.shtml
