I don't think Sony could afford Activision. Its own market cap is 133b$ USD, which is a lot, but it would still have ended up being a very high-risk buy/merger. I'd be surprised if they ever had any acquisition talks. Activision is so big that only titans like MSFT could afford to buy them outright.

Xbox is still behind Sony on the multimedia market. Don't underestimate sony.

Still, buying a company that's half your size is quite a chunk. And Activision is anything but a save purchase with the recent scandals. I highly doubt Sony would take such a risk.
