I think this is a permanent feature, which is kind of neat. Especially for people who plan to bring up a few alts.
This is going to be a lvl 80 dungeon. At least auto scaling up here (which, actually, was something they had originally said was going to be in all of PVE, so maybe there's something Jam can be happy about ;-) ) allows everyone a chance to play while still allowing Anet to make a dungeon aimed at people wanting more challenging things to do at lvl 80.

Getting back to the gear grind stuff, I've thought about it some more and it occurs to me that, as I mentioned in my first post on this topic, it had always been their intent to introduce higher levels and thus more powerful armor and weapons to the game, but that it was originally intended to be done with expansions. Unlike Factions and Nightfall, the new powers would come from that and not necessarily new skills (since too many skills is part of why they decided to make GW2 in the first place). The key here, as others have mentioned in this thread already, is that we don't really see the current implementation of level and gear acquisition as grind because you can pretty much get everything you need to succeed at PVE by simply playing PVE the way you want to. And that's how they are implementing the new Ascended armor (early parts of the dungeon won't require it and success in there will reward you with the new armor) and will probably be how future upgrades will work too. And with the downscaling system, it doesn't matter how high levels go as the old content will still remain relevant.
Looked at from that perspective, this isn't gear grind, it's the new expansion model, which is to say, more of what we already have with GW2 but new areas to play in and new gear mechanics to learn. It remains to be seen, of course, whether it actually continues to feel (required) grind free as GW2 has so far, but I don't think they've actually said anything (in context of the above) that breaks the promise they made about no mandatory gear grind. And I'm finally feeling a bit better about them increasing levels in expansions now.
