Bioware probably keeps track of how many people play and things such as general reception of the game as a indicator of how many people show interest.
The point.
Your head.
I don't think the OP knows that DA: I modding is pretty well underway. Tools are being fan developed. It's not polished but again, it's just about two months since the games release...on a brand new engine...an engine nobody thought modders would crack.
And though Frostbite is difficult - there is something they have that fans don't. Official licensed tools to be able to add content.
Inquisition mods will never be substantial.
I don't really see what day 1 DLC has to do with anything. That's part of the launch when it exists. How does the existence or nonexistence of a day 1 DLC change planning for when to release other DLCs? Beyond maybe tying up the devs for the certification period with work on the day 1 DLC, that is. It's not like the day 1 DLC can extend the high interest of the initial release.
DLC development begins before the game ships. If the dev team is tied up with the day 1 DLC they can't work on the next DLC. This is common sense stuff.
I also don't get why you don't think that waiting a few months for the first post-release story DLC isn't common for Bioware. RtO is the only exception I can think of. (Firewalker was planned for day 1 but got delayed, IIRC.) Since they didn't repeat RtO's release timing with their next four games and DLCs, it looks to me like Bio doesn't think that timing worked for them.
Why can no one here read? I've said several times that I'm talking about news of DLC, nothing more. Inquisition is being forgotten by gamers every day. There are half a dozen AAA games coming out in the next few months that will edge Inquisition to the fringes of the gaming market.
