Reading his previous tweets, why would he have been in Sweden to sign the contract for an EA job if it wasn't DICE-related? Do they (EA) have that kind of offices in Malmö or Copenhagen?
The head of the EA Games Label is Patrick Soderlund, who used to work at DICE.
They're also using DICE's engine and help develop it as well.
I wouldn't be surprised if DICE is helping out a bit though. EA shares resources a lot. Like 15 people out of Danger Close worked on Bulletstorm.
