Yes
No, unprofessional was what Phil did: to publicly mention their business talk with Sony which should remained confidential.
And even worse, Phil did that apparently bullshit contact basically to lie their investors, regulators and ABK customers, which is even worse making them sound as if they wanted to keep CoD multi to pass the regulations and close the acquisition when they wanted to turn it into exclusive.
Jim did what was needed: to be clear and mention that MS was lying regarding their plans for CoD and PS, and to clean Sony's name regarding the regulator investigations and the hypothetical future announcement of CoD going exclusive.
Fun fact: Destiny has the record of the biggest selling (worldwide) new gaming IP ever.
Not of FPS, but of all genres. Not this gen, but of all gens.
