It's not new news. It's no secret that WoW numbers have been declining for a while and CoD pre-orders are lagging previous years. I saw an article a while back speculating that the lower CoD numbers were due to GTA V as well as franchise fatigue. They also have Skylanders competition from Disney now, a lot of debt they didn't have before, and rather quiet releases from Blizzard. The problem with banking on a few huge franchises is that when growth stops and sales start declining, there's not a lot of hope for upside until they can come up with another huge franchise to suck dry. There will also likely be increased trading volume once insiders who started ahead in the share buyback deal can unload shares that were once snugly sat on by Vivendi.
ATVI will release DESTINY in 2014 and NEW TITAN MMO in 2015(improving it). CALL of DUTY preorders are NOT taking DIGITAL downloads into consideration. I believe that the new Call of Duty: Ghosts will do well. Battlefield 4 will eat into it a bit more this year. SKYLANDER's SWAP FORCE will perform very well against INFINITY. COD numbers may not be as good as last year, but they will be better than expected due to DIGITAL downloads which is great for ATVI and bad for retailers( reduce the middleman's profit).
