As for Jacobs' comments on the reasons for him leaving, we don't find it out too much, but he did have have this to say:
Early in May, Electronic Arts let me know that they wanted to make some changes within the Games Label and as a result of those changes I have been out of the office (and out of touch with the team, game, etc.) since that day.
However, if you are looking or expecting me to damn EA or anyone there, you will be sorely disappointed. Over my 23 years of making games professionally I have refrained from attacking the competition, former and/or current partners, other game developers, etc. except on a few very rare instances. I have no intention of breaking with tradition at the present time and I hope my track record in this regard remains unchanged for the rest of my career.
We will be keeping an eye on Jacobs' blog for the additional posts he has promised.
