That is not a Longbow, that is a Hurlbat ;-)
I expect the minis to be available in early 2012, first batch will contain the Tarasque, the Gnat, the Xiphos, the Geruda, and the Hurlbat. In the following scales 1/300, 1/450, and 1/900. The Tarasque will be around 50mm (~2") tall in 1/300, 33mm (~1.3") tall in 1/450, and 17mm (~0.7") tall in 1/900. Larger versions are planned if the others sell well: 1/150 (N-scale), 1/100 (15/18mm scale), and 1/60 (30mm scale). I'm aiming to keep the scales consistent, the Tarasque is the heaviest Mech available (without going into Super Heavy Mecha categories), the Gnat is the Lightest. The Tarasque is 15m tall (~45'), the Gnat will be around 9m tall (~30') or 3cm in 1/300.
Shane "Sandman" will be showing off the 3D sculpts in the near future.
The art will be available under an Open Source license (probably the Creative Commons Attribution-ShareAlike license), any 'fluff' text and game rules will be available under the Open Game License (OGL). Game book pdfs will be available for for free.
Background will be a corporate world/system that can be placed into any sci-fi setting featuring Mecha and Cyberpunk. Rules will not be a selling point, but will be developed in an open format so that a 'complete' package can be offered.
The last four months have been very busy for me, so I've not got a site ready yet, I hope to get something ready in the coming month.
I don't want to step on the toes of the powers that be, so I'll try to comment as little as possible on this forum on this subject.
