well, there's some intersting posers there, I'm happy to put some or all of them to Tharg should I get the chance, but here's my provisional guess as to the answers:
1) soonish, I'd guess.
2) Mr Fraser's most recent postings on this board make it pretty clear that for various reasons he's almost certainly not going to be drawing Dante in the foreseeable future.
3) I suspect this a question for John Wagner rather than Tharg, but I'd imagine in the wake of the generally positive response to HoV that it's promising.
4) I suspect the answer's "oh, god, please don't mention that" but this is potentially the most interesting question to ask, so I'll definitely be posing that one if I get a chance.
5) because Frank says so.
