Interesting idea, but they've picked up Playdom already and if you listen to their analyst calls you'll hear that the investment community isn't sold on them owning game/tech assets vs. licensing them.
I would rule out:
- Google, Facebook, Microsoft, Sony, Valve
Just doesn't fit the acquisition profile for those companies IMO. The Popcap guys are smart, and for a billion dollar valuation, the acquire'er would have to have some sizable synergistic advantages afterwards.
Not Valve? I dunno, it seems possible to me, but I think it's probably one of the companies trying to move into casual games, which PopCap are great at, I assume EA.
Part of the reason that they were willing to pay so much was because they have a lot of international money that they couldn't easily bring back into the US. Popcap is in the US so they don't fall under the same issue.
Still excluding the tax savings they still overpaid by all accounts, have a long history of wildly good and bad acquisitions and need to give wp7 every advantage they can. There's no way you can rule Microsoft out at this point they've got to be one of the front runners.
They already seem to have a good WP7 relationship (Bejeweled Live is actually written by them, as opposed to EA Mobile [moderately rare for small platforms], and PvZ just came out last week). Make of that what you will.
Why do you think Valve couldn't afford it? They are a private company and so don't have to release revenue figures, but they make billions in revenue a year.
If Valve bought PopCap then it would be like a Reese's Pieces. Two already great tastes coming together. PopCap is the perfect cultural infusion that could get Steam opened up to a larger (non asian 17 year old male) market.
EA (7.5B market cap)
Activision (13B market cap)
Microsoft
Sony
Valve (I somehow think they couldn't afford it)
Tech / Social:
Zynga
Google
Facebook
Foreign? No idea here.
