Yeah no mention of any sort of "hey, if you bought the previous Dutch DLC you get this one for free for a limited time" or anything like that, just straight-up "buy him again!" And you know all the voice lines are going to be the same ones we already got in the current version as well, so it won't even have that going for it.
Chances are that because I'm a damn fool I'll still end up getting it anyway, but I might at least wait a little to see if there are any new voice lines at all. But it's hard not to see this as the calculated move it is. They knew full-well that if they put the original Dutch skin out first rather than the "old Dutch" we got that everyone would have just bought that and be done with it. This way they know there's a lot more chance they can get people to double-dip.
I get it, it's Dutch. But still, I doubt too many people would have been disappointed with Harrigan or Royce, or even a character from the comics, perhaps. I'd totally be down with an Enoch Nakai fireteam DLC too.
