Since this deal is huge and globally important, the deal will also undergo scrutiny in Europe and it will remain to see what parts of the deal survive the plans. The investigation in this deal should cover many areas of the business and what the combined company could look like after. Significant questions that should be expected to arise are whether or not Microsoft's acquisition of such a huge global company like Activision Blizzard would create such unfair competition that it would harm their rivals by limiting access to products and exclusives. It could come down to whether Microsoft being in the console business with hardware, in addition to owning several of their own major IPs and companies, could absorb everything in the Activision Blizzard portfolio without doing significant harm to other companies (and the consumer market).
