I'm neutral on ATVI here. They're not particularly cheap considering growth is a question mark. The Hawks franchise and Ride looks in big trouble. Can next years CoD grow past this years? I wouldn't bet on it, especially if the rumored setting of Vietnam is accurate. Particularly in Europe that's not as interesting as Modern Warfare. And the music genre looks to be in steep decline, with DJ Hero likely a bomb considering it's heavily discounted already. Their console division, ex MW2, has been a disaster this year with bombs and delays.
OTOH, I have high hopes for Blizzard next year and Battle.net, which I expect will start charging Live type subs and will be a high margin earner. This could certainly offset console weakness and Battle.net contribution isn't being talked about by any analysts... yet, AFAIK.
$10 is as low as it's likely to go so I'll be more bullish if it drifts there.
