Saw this new ultra-lite tent (really a zelt) on sale in Rally Grass, Fukuoka last week for 35,000 yen (just bought a MacBook there as well, so though I was tempted, I didn't bring one back to Korea!). Weight: 710 gm Dimensions: 210cm x 100cm x 105cm high. URL: http://heritage.co.jp/gear_models/zelt_crossover_d.html This features very lightweight poles. Floor is same material as dome. Would prefer to see the door on the other side, and the vent further from the door. There is no bug-net door. Tunnel vents both front and back. Quite impressed. 
Heritage makes some very fine tents that have long tempted me, though as I mention above, this is more of a zelt
