Well, yes. When a company commits to releasing something on a schedule and then suddenly doesn't, people are going to be angry and disappointed. It's best not to commit to a schedule when you're not sure if you can keep up with it.
But it's also a communication issue. Things happen, we understand that, but a heads up like "we can't release a follower this Friday, sorry" or "we released a trailer and that will take over the Follower Friday release" can do wonders. People will still be angry and that's their prerogative (though I'd prefer less venting on the forum over stuff like that) but they can't say that BioWare just hushed up and "ignored" their fans.
Also, I want to say that I appreciate your communication with fans, Allan. It does really feel like you listen to what we have to say even if we're just the super vocal BSN minority 
I also think the majority of people in this thread don't understand why this is a valid concern. I'm not personally attacking anyone. Allan is very helpful in his role and he does it very well.
But people are behaving like this is a company that is not coming off of 2 games that have alienated the majority of gamers. That's a fact. You may have your positive opinion on those games, but they were panned by the majority of gamers. So much so that there was a rip about ME3 on an HBO show a couple of weeks ago. Marketing for DA:I has to be better than this. I say this as someone who really wants it to succeed because I'm so invested in the lore at this point.
Bioware's stance on DA:I , even back when it was called DA3, has been that they won't show anything until they were ready to show it. It was a good stance to take because it showed they understood their shortcomings before. They promised something they couldn't deliver, and that really bit them in the ass. Then came the PAX video. It was exactly what they needed to show. 30 mins of pure gameplay. That is what gamers want and that is what is going to win them back. I think they faltered a little bit by relying on word-of-mouth and video feeds of people in attendance, but that is debatable. I know I've personally have linked that video hundreds of times in countless message boards in defense of Bioware. I feel they should have released a version of that in HD with Laidlaw's commentary that he does so well. But that's just me. It was great none-the-less. But now since January I feel they have completely broken down with Marketing.
- We were told we were getting Dev Diaries. Someone got sick
- They announced Follower Friday, released one, then forgot the next one (THE VERY NEXT ONE)
- At this point I'm fully expecting to hear, "Well, we had a follower Friday all done but my Mabari ate the follower"
Not to mention that there were countless articles released that were giving out misinformation. One or two I can understand. But there was wide-spread misinformation going on. That was a breakdown on Bioware's part. I guarantee you that they've started to think the same. As people have mentioned, this is very reminiscent of the build up to ME3.
So now here we are. Pre-orders are ready and I'm sure tons of people flocked to get it. I'm a fan boy myself. I wanted to run out and pre order on every system i could (joke. i'd only play this on PC. I'm not a savage). But then this happened and I started looking at the big picture and decided that I need more assurance that bioware can deliver. I'm going to buy the game. Probably day one. But I'm not pre ordering just yet. They haven't earned that from me yet. Repeated blunders in the marketing are the cause. To say I don't "get it" or I'm being "bratty" or saying things like "We got Gaidered" aren't helpful to anybody. Twitter may hold the illusion that the Devs are your personal friends, but they aren't. They are people selling a product that need to prove to a lot of people that they actually "get it." Name calling people with actual concerns that they can back up, instead of holding their feet to the fire, is not going to change that.
And just so we're clear. I was not voicing a concern that there is a lack of female characters in the marketing. That nonsense gets far too much attention here and was mixed in when I was expressing my concerns and diluted (I feel) them a bit.
