For years and years before Morrowind there was bigger and better Elder Scrolls. Something changed however with Morrowind with that Bethesda added a broke 3rd person view that was broken and hard to use but doing that one thing increased sales and made the Elder Scrolls a almost household name in the gaming community.
This and Bioware adding 3rd person to the games actually helped make the once horrid Western Lackluster Games and RPGs that often gone ignored into primetime and took the lead over the Japanese counterparts.
After each Elder Scrolls game and during play test Interviewers Todd Howard always admits in interviews he is surprised so many people like the 3rd person view. When ever he has an interview and they ask what surprises him about the success the topic of the 3rd person view always comes up.
I'm most likely late on posting this news but its not just the news that the Elder Scrolls online version is ditching 1st person view its the news that even moderators here for years had wailed the 1st person view is as possible as ever with hardcoe fans following along but is this a sign that the next Bethesda games will focus and strengthen the more popular 3rd person view?

I don't know how much 3rd person helped Morrowind, but I'd guess other factors more than that. First, gaming generally had become much less niche and more mainstream when Morrowind was released compared to its predecessor, Daggerfall, released some 6 years earlier. Additionally, it was the first ES game released on multiple platforms (PC, XBox) giving it a wider potential market. It had some new features (other than 3rd person) such as mod support, a more detailed (albeit smaller) world, and fewer bugs that its predecessors. Why single out 3rd person as *the* feature? Don't get me wrong, I have nothing against 3rd person; I just find it odd that it would be the one feature above all these others that made Morrowind more successful, in terms of sales, than its predecessors.
I'd also disagree with the assert that western RPGs of the pre-Morrowind era were "horrid" and "lackluster". Yes, there were admittedly a lot of bad games, but there are those in any era. However, many very well regarded games from this era, including Fallout, Baldur's Gate, Planescape Torment, Daggerfall, and others.
I'd also consider the possibility that Bethesda will not ditch first-person view in any future ES6 and that Zenimax Online's decision to provide a more limited first-person view functionality is due to ESO being a different type of game and with Zenimax Online having different goals and expectations for ESO than Bethesda had for Skyrim, et al. and will have for ES6 than any general move away from first-person perspective.
