It's always been like this, and it isn't limited to EA, or even the video games industry, it's a battle that takes place regardless of the product being promoted.
Instinctively you'd think there would be overlap in objectives (and to a degree there is), but you need to remember that each department's performance is being assessed by very different measurements; the devs are being assessed by the quality of the finished product, which needs to be good enough to sell a baseline number of units, meanwhile marketing are expected to get a lot of exposure for a product, and generate new business, regardless of product quality.
I work in
PR and it can be a nightmare when a product team wants to tweak a press release to make it slightly more relevant to their core sector. The tinniest change that makes a press release 1% more interesting for a core set of consumers, could potentially make it 90% less interesting for other groups.
As an example, last week I was working on a release to celebrate a client attaining a top standards rating in their sector. Our draft copy was exciting, but we still ensured that it was factual throughout. The client decided that the word "award" and others similar, couldn't be used in the context of industry standards rating, and we had to reword the release. The final copy is no longer an exciting story of achievement, it is a boiler plate statement about standards compliance. One small change has meant that story will probably only appear in certain niche titles, and the client will be demanding why they didn't get more media coverage!
This is why the areasof Madden that interest us the most are not the things that appear in trailers, get announced on stage at E3 or EA Play, or form a core part of the marketing strategy. It's because the guys in marketing have to appeal to the widest audience possible, and get a big fat stack of media coverage, rather than a thread on OS praising EA.
Wait for the deep dives. Like Rex said in the interview, realistic gap play and zone coverage pattern matching is not sexy, and marketing are not going to make it their centrepiece, even if they were the only two additions made to the game (which they're obviously not!)
