Destiny doesn't really bullet point out like this. The EDZ is supposed to be >2x the Cosmodrome, and has far more things to do in it (adventures, lost sectors, flash points, etc) and feature far more active players in a space than D1. Most strikes since vanilla Destiny released have featured rotating or branching encounters vs. the fixed in the original game - does D2? The area covered in the new strike is immense, far more than anything in D1. Is the raid CE sized or WotM sized? Will challenge modes be there from day 1?
We don't know how many maps, modes, social spaces, etc. But we do know the one social space they've shown will change and evolve over the course of the game, and has several activities built within it, which already makes it more interesting than any of the ones in D1.
Reducing all that to a bullet list is a disservice to honest discussion about it.
The only things that I can think of that you could bullet out well are the class/subclass, number of missions and volume of Crucible content. (I'm quite disappointed about the class/subclass situation, myself).
