EA denies having any hostile takeover intentions towards Ubisoft... but then, Hitler said he wouldn't invade Poland. And EA are certainly closing on their borders.
According to Reuters, EA is keen on adding to its (almost) 20% share of Ubisoft and seeks representation on the Ubisoft board. Officially, EA are sitting on the fence, stating that it wants to "keep all its options open regarding this investment in Ubisoft and could buy more Ubisoft shares, possibly a controlling stake". Nice of them to let Ubisoft know where they stand.
