If it doesn't have the Open World feel at least they yes I will probably drop it. However, as people have implied "Instanced" does not necessarily mean raiding or dungeon. This could still be popped instances via an item or quest or be tied to Faction/Grand Company levequests. I'm sure someone already mentioned this but BCNM, ENM, KSNM, ISNM were all instanced. I have a feeling grand company leves will focus more on this as they are now becoming the main storyline. They talk about the Ifrit battle as a "Battle" which I interpret as being like a BCNM or similar to an Avatar fight in XI. And XI did in fact have a lot of Raid type content such as Dynamis, Limbus, Assault, Einherjar etc. So I can imagine more of those things this time and less HNMs like LoO, Vrtra, Fafnir, Nidhog, Jormy etc. which 75% of the population never fought anyhow. They will probably keep NMs along the caliber of Leaping Lizzy, Stray Mary, Mysticmaker (for all you BLMs out there ^^)
