That's a good question - one of the big deals with the reconfigured 'M8R' aircraft was that the row numbers lined up, so my guess is that there might be a little bit more room, then again if these had more legroom the seats would be listed as preferred.
I'm going to be on a MD
-88 tomorrow evening from ORF to ATL
. If no one answers your question before then I would be more than happy to take a look at those seats for you.
Also, are you sure the bulkhead seats are gone? Delta usually holds the bulkhead seats until day of departure. They probably show as unavailable if you're trying to book your seats online. I would call reservations and find out (perhaps a DL
insider here can give you a scoop on those seats as well).
