The main cause of delays is initial optimism - BFL is doing this from scratch, so it's even more of a challenge. For the first ASIC generation of devices, these delays from BFL may actually do good for the mining ecosystem, by allowing competitors with initial late release dates to also have enough sales to make it worth having invested in product development. Out of the delays, I'm sure the BFL SC line will be more polished than what was originally planned. Until then, the website appearance isn't really a priority, and that's what I meant above. For me, it'd be scary if there wasn't a product starting to ship, and the website was 100% awesome.
