Thanks! It's a good read, but it doesn't assuage my biggest concerns yet. One of which is that the worlds are still far too small. They said on stage that the European Dead Zone is the biggest area they've ever made, and twice as big as Destiny 1's biggest zone. My concern then was... doubling something tiny still isn't impressive. And if this comment from the article you linked is anything to go by it's not like the EDZ is the normal size for Destiny 2 zones from now but a one-off:
And my second big concern is something that... I have no idea how they'll convince me to not be worried about. It's that Destiny 1 had four planets at launch, and even today it's still only four planets, but with one of them re-skinned? (I stopped just before TTK) and an explorable ship. So if they're once again committing to small zones that you can learn by the back of your hand in a single sitting, with only one of them noticeably larger than before, AND there's only four zones at launch again, then I absolutely need them to promise that this time around new zones and planets will be added with every single expansion, even the small ones. These are tiny zones by MMO standards. It should not be this difficult. And with all this talk about a new engine and a whole new game being necessary to speed up content creation, they have no excuse not to make this happen.
Sadly even their website states that Destiny 2 expansions will add "new story missions, strikes, raids, and PVP content", with absolutely no mention of new exploration content. So I'm terrified they're about to repeat the same mistake, and am hoping they've just done a bad job of conveying their commitment to solo PVE content so far and will be addressing that soon.
