It seems that this is not where we will have a final solution that satisfies everyone in the event that Activision Blizzard is acquired by Microsoft. The Federal Trade Commission (FTC) recently requested a court order to stop the deal and now a US judge has granted the request and temporarily halted the acquisition of the creator of the popular game Call of Duty.

As mentioned here, the North American Federal Trade Commission has applied to the United States federal courts for a court order to prevent the acquisition of Activision Blizzard by Microsoft.  And that work has now paid off, according to Reuters, until Tuesday (13) a US judge approved the Federal Trade Commission's request and temporarily halted the acquisition of the gaming giant.  In addition, a hearing was scheduled for the next week.
Details are that the judge in question, Edward Davila, has scheduled a two-day meeting on the FTC's request for an injunction for June 22-23 in San Francisco.  The US entity's intent with this order was to prevent the deal between the Redmond company and the game maker from closing on Friday.

After a hearing in late June, the federal court will decide whether or not an order is necessary.  That injunction has now been issued,” Judge Davila said.Necessary to maintain the status quo while a complaint is pending (and) to preserve the ability of this court to order effective relief in the event it determines that an injunction is necessary and to preserve the ability of the FTC to obtain effective permanent relief in the event of prevailing in your pending administrative process".
In contrast, Microsoft and Activision Blizzard are expected to present legal arguments against the potential injunction on June 16, with the FTC's response expected on June 20.
