I'm on an A321 next week with what I assume is the newest configuration - the one that adds two seats next to the starboard aft exit door near rows 26/27. A couple of questions I hope someone can answer:

-- Why can't I find any seat maps (including on seatguru or even delta.com) that shows these two new seats in row 26? Oddly, delta.com has seat maps for both the 189 and 191 seat configs and neither show the two new seats - it shows a completely empty row next to the exit.

-- Most importantly for me, how is the legroom in the "new" row 26 on the starboard side? I have the golden 27F on my return flight, but don't have any experience with 26E. Should I hang there or put in for a C+ upgrade? Which, with my luck will certainly default into a lovely middle seat. I've got tons of drink vouchers so I can enjoy a drink wherever I am.

Here's the seat map I'm referring to. I've done extensive searches looking for details on the new seats without luck so thanks for any guidance!
