Yes, just spoke to 1K line. Turns out there are middle seats left but technical group is having trouble releasing them (not sure what that means) so they will be released 24 hours prior to flight.

However I am certain there are some E+ blocked middles that are available if you call reservations and have them check into that for you. Upgrades for 1K's will start tomorrow and others will follow so keep checking back after the 100 hour mark and you may see a vacated E+ seat that you can snag.
