There is nothing in this thread about board design.
...if and when BFL starts releasing documentation.
I read something about "2 weeks" for Docs and samples to Devs on another thread About BFL chips. 100% escrow or something. Who knows, but it'll be hard to convince people until they "put up"; if and then, the race will be on for Avalon 2.0
I haven't heard any details about a second generation Avalon chip yet. That's not to say it isn't in the pipe, but I would love a link to some technical details if you have them. The Avalon chip sales were extremely successful even before any information was released; some community members released preliminary layouts even before knowing the pinout of the chips. While BFL hasn't exactly been prompt compared to their original deadline for mining devices, the chips are proven at this point and there shouldn't be any reason why the issues that BFL has ramping up after redesigning the Single PCB and hardware will significantly affect chip timelines.
I won't say I'm not worried about the 100 day timeline slipping a little, but then I'm worried about Avalon being able to deliver chips to the April 16th orders within the next week and a half to meet their 10 week deadline. I would say that people who buy BFL chips have more to worry about from Bitfury, KnC and Avalon V1 than Avalon V2 at this point.
