The latest Chris Ware volume I've seen is Acme Novelty Library No. 18, which is typically bleak but very affecting, worth a read.

There's going to be a huge shift in mainstream understanding of games and comics in the next decade or two. I think comics have pretty much got there in the UK. The LRB ran Spiegelman's In The Shadow Of No Towers, you regularly read reviews of Clowes or Moore works in broadsheets, and most bookshops have sizeable sections dedicated to comics

I don't know, it's the oft-quoted 'failure' of graphic novels that after the mainstream breakthroughs of Watchmen and The Dark Knight, nothing else has really escaped the chains of the 'genre fiction' label. The Sandman collections were supposed to be the next volumes to break the mould, but they didn't manage to shrug off their pigeonholing as goth fodder, and there's yet to be another graphic novel that looks like troubling the bestseller lists.
