My predictions for the Nxxxx hints
Airbus A320
N64xxx - Alaska (N640VA - fences), Spirit (N640NK - 2007 to 2014 livery, WL) American, U.S. Airways (2005 to 2014 livery), America West (1996 to 2005 livery), Virgin America
N85xxx - Alaska Fly with Pride Livery (N854VA)
N72xxx - Avianca Pride Livery (N724AV)
N74xxx - Avianca standard livery (N743AV)
N32xxx - Delta (N327NW), Frontier (Neo), Northwest 2003 livery, Northwest Bowling Shoe livery
Airbus A321neo
N44xxx - United EvoBlue livery (N44501), American
N92xxx - Alaska (N921VA), Alaska Most West Coast, Virgin America
NG really loves Alaska Airlines lately. Also seems like we'll be getting two Avianca A320s, with hopefully one of them being a standard livery. I'm glad that we're getting more U.S. A320s, but there really could be some better selections here (e.g. United, Allegiant, Frontier, even JetBlue). I'd rather see these Alaska releases spread out more over time for the sake of getting more variety in U.S. carriers.
NG seems like they want to complete the Airbus fleets for U.S. airlines per carrier (first with Spirit, now with Alaska and possibly Delta as well - hopefully United is soon). The N32xxx A320 and N44xxx A321neo are definitely interesting to me but other than those, it's all pretty meh. I wonder if all these Nxxxx A320s all of a sudden in the past couple release sets means that we'll be seeing less of these A320s next year since it's the "Year of Classics" I'm very intrigued as to how next year will play out.
Seems like we'll be getting some more ANA or JAL 787s. I'd really like an ANA standard 787-9 re-release.
