I think the only ones "entitled" here are the players eager to kick oldgen players to the curb so they can get "better" dlc.
We've been through this already multiple times - that's no less of an entitlement than asking for content on a platform that, at this point, serves only as creative and financial impediment.
Also - hyperbole much? Nobody "was eager to kick oldgen players to the curb so they can get better DLC".
I wonder how many next geners gloating also complained about the dlc exclusivity for Xbox one.
Apples and oranges. While they're a problem in themselves, exclusivity deals are not holding devs back on either technical or financial level - in fact, the exclusivity deal with Microsoft existed precisely because they helped to finance the DLC. So there's at least one benefit to that - while there's no benefit to developing ports on old-game consoles, other than not annoying a small (and ever-shrinking) old-gen player base.
And I'm not saying that they shouldn't be annoyed - I'd be annoyed too, especially if the news crashed right before the DLC was out (and at his point we have no idea when it's going to be released) simply because I'm invested into the story. Heck, I may even be annoyed IF it turns out that the DLC won't be released (or released at the same time) in my part of Europe, which is a - small, but still - possibility.
Would I'd be so vocal about it on the forum about this? Knowing myself, likely not - there would be no point. If anything, I'd rather be focused on either getting more information or finding a solution (just like I did when it turned out that I can't pick a language version I wanted).
