By the looks of it, the DB forum of Comicvine isnt what it used to be, but I expect it may see a bit more traffic again soon.
Toriyama died on the 1st of March from a subdural haematoma, as I understand it, as a complication of a tumour.

I dont know about anyone else, but this is genuinely the first time I’d been truly saddened by the loss of a celebrity. So I thought I’d make my own little goodbye to the man who’s work I enjoyed so much.

See you one day in Otherworld sensei
