Donny2112

Possibly Sales-Age's biggest data compiler.  Not so much of it is easily accessible online, but his Japanese software data goes beyond what I've done, and he keeps good track of what we learn from NPD numbers as well.

His web site, with a few of his regularly-updated graphs.

As of May 16, 2009, I have decided that until I learn otherwise I will assume donny2112 is in fact Donny Most.
