I wasn't initially going to comment on Warner Bros' purchase of Turbine, for lack of any obvious immediate effect on the studio's MMORPG's. However, on further reflection, I'm wondering if the purchase hasn't already caused a bit of damage on DDO.
Turbine's official explanation for last week's offer wall fiasco was that they wanted a no scamware/spyware policy but somehow failed to implement it before pushing the system live. The bit of information that we did not have at the time was that the studio was a week away from being purchased - presumably a bit of information that the DDO team already had. My guess is they rushed the offer wall live before it was ready in an attempt to get it out there before the purchase was announced. If I'm right, they were afraid that the wall would be seen as a mandate on high from the new owners, and that this would only further hurt its perception amongst the community.
Unfortunately, the rush job meant that the wall did not have the best chance at success. This is a problem because the original version's failure to keep the scams away will color perceptions of any future version of the wall. Worse, the incident could affect Warner's view of the game's future potential - "oh, those freeloaders will revolt at any attempt to make their game profitable, so we should just kill it".
Perhaps that's a far-fetched scenario - Warner will probably leave Turbine alone as long as the studio remains profitable. However, this could have an impact in the future, especially if the hypothetical Harry Potter MMORPG is the reason why Warner purchased Turbine in the first place. If the DDO team gets stripped down to send its best people to work on Harry Potter, and the remaining dev team can't deliver as much content to a game that literally depends on new content to survive, this incident could be the beginning of the end for DDO.
