Yes, I'll be writing more books, more details later; as for a 2nd edition, well, the 1st edition is probably more useful in the meantime than you might think. Lets say you install bcc/BPF tomorrow. Ok, now what? The hardest part is to know what to do with these superpowers. Apart from the provided scripts in bcc, the sysperf book has other DTrace examples that you might need, and can then port over. The hardest part of DTrace was knowing what to do with it, so all the prior DTrace documentation will be good material to browse and be inspired from, including my DTrace book. Many of my bcc/tools originated as versions I wrote using DTrace.
