Wachaaa - that one's done.
We're nearing the end of the series now so the next two and a half volumes cover the whole of the final showdown. It's classic jojo so they make peace and end all rivalries calmly, might still be worth reading though.
Within a few more months we'll get 45 out, and then 46&47 a week after that. No idea about exact timing so don't ask.
Volume 44:

With other jojo stuff, there's a HQ JoJolion Volume 1 just about ready for release and work's very well under-way on a HQ Stone Ocean Volume 1. Kewl recently finished Over Heaven if you're a side novel fan too.
