No, end of October is where the support material is guaranteed to be complete. This implies that it will be made available as open source as early as Bitmine has it - essentially DIY developers will have identical access to the relevant documents.
Since chip sales are part of their business, Bitmine has a vital interest to provide all available support to developers. That's why I am confident in this commitment enough to include the guarantee as part of the offer.
Code:
Product Description
Developed on 28nm HPP process from Global Foundries
Custom IC package with power bars for low voltage, high current feeding
Configurable in binary tree or daisy chain mode for distributed work with up to 4095 ASICs.
Standard I2C interface
Hashing power* of 20 GH/s in nominal and 40 GH/s in Turbo mode
Power usage* of 0.35 W/GH in low power, 0.6 W/GH in nominal and 1 W/GH in Turbo mode
Supply voltage* of 0.5V in low power, 0.65 V in nominal and 0.75 V in Turbo mode
Mass production available starting from the last week of November 2013
* Please note that while we took the highest possible care in doing accurate and conservative
simulations, the real performances of the final product could vary by a +/- 20% tolerance.

How I can miss that 
End of October. In this case, we have very limited time to design.

Situation:
Designed from scratch, Bitmine’s Coincraft A1 is a third generation Bitcoin Mining IC developed by Bitmine in co-operation with a team of expert engineers from Innosilicon. Targeting the highest possible power efficiency, the A1 is made to be deployed in huge binary trees structures within large scale private or public mining pools.
Available in mass scale production starting from the last week of November 2013, the A1 employs cutting edge 28nm HPP technology from GlobalFoundries and ultra low voltage transistors, packaged into a custom engineered IC package that features our proprietary PowerBar technology for very low voltage, high current applications. Whether you want low power usage or high performances, the A1 fits perfectly both.
Our ASIC is the result of more than half a year of engineering and analysis of current systems limitations and predicted future of Bitcoin mining. That’s why we are confident it will be the best ASIC Bitcoin Miner design ever to be available on 28nm technology.
Detailed datasheet with the specifications of the package outline and the interface protocol will be released to buyers during the month of September.

Focus
Looking for hardware / software designers and miners willing to work together on a DIY Open Source Hardware / Software project that will develop a smaller 4 chip board that can turn 80 to 160 Gh/s for the group members and also the rest of those in the community who would be interested. Open Source would be released only after things are fully tested and working to the whole community. Production to take place upon delivery of the chips could take place at various fabricator worldwide.
Response
The group buy would be a start to finish development not just the chips.
Evalution
Miners would be shipped to members of the group buy after production is complete. Some members can do the fabrication as well and produce the miners. It would be up to each member of the Group Buy to decide on their preference for production.
