The pressure is on now though... This next story DLC better be fantastic and take full advantage(all the bells and whistles) of being exclusively on current gen systems.
If they release a DLC that could've been handled by the PS3 or 360, like Jaws of Haakon, they deserve to be taken to task for the decision to drop support.
I am going to answer this comment.
If you are expecting the next to be insane compared to what is already out, then likely you will already be disappointed. The reason for this, is DLC is generally content change with a bit of code change (it used to be on last-gen that it had to be content only, because it was required your DLC ran on the shipped version of the game, not the patched version). While the industry works to move away from this I expect we can see different DLC but simply speaking that change will not be instantaneous.
Regardless of that, you still have to consider something like PC, we have minspec requirements to consider. So you cant push the envelope that far.
Next ill state there is other things to consider, something like you have to tie your content into the exist game in some sense, not all DLC can be self contained. Take something like a new piece of armor, if that thing has a new VFX then you could be putting additional memory load on your already streached sections of the game, even though it is something introduced by the DLC. On a minspec PC if you run out of memory the game can start paging to the hard drive, you might get performance problems but the game wont crash. Do you think something like this exists for both last-gen systems?
