Yeah, I was wondering why No CFT was included in your poll!!
And I can further see that by the inclusion of EPE/enhanced engines being listed TWICE in your poll you might hold a slight bias in that department eh??
Otherwise, the whole definition of what 'Block III' entails is actually pretty undefined and relative imho.
I mean, the planned next-gen Type IV computer + next-gen displays integration alone won't necessarily translate to a so-called Block III, will it?
Yet for marketing sense, perhaps Boeing could better clarify a block type upgrade designation path...e.g., a block II+, II B, IIIA, etc?
In my assessment at least though, the credible 'next-gen' Super Hornet will need to offer a CFT configuration capacity, period, as a baseline. Then upgrade from there.
Simply, the CFT will allow the platform to better exploit a wide range of other next-gen upgrades/ehancements... such as: the proposed centerline Weapons pod (or centerline IRST/Recon pod, or Escort jamming pod), improved ATFLIR field of view, improved aerodynamics (leading to reduced annual fuel consumption for same number of hours operated), reduced RCS, increased cruising speed, improved agility and acceleration (vs performance of wing-EFT equipped SH), greater lift/reduced wing-loading thus improving control @ higher-altitude maneuvering or lower approach speeds, and increase overall flexibility and combinations of the Tactical load-out configuration.
The CFT might also be an incentive and amplify the justification for investing in the proposed F414 engine upgrade as a package deal.
Anyway, most likely there will be an 'incremental', prudent upgrade path to look for, over the next 3-7 years (by 2020) and not so much an all-inclusive ultra block III SH with everything envisioned by integrated into the model all at once..
So I'd list priority as: Type IV mission computer, CFT, displays, common MAWS+laser warner (either being skin-mounted or externally integrated), Radar/ESM enhancements, enhanced engine, wing and hard point aero-dynamic enhancement (similar wing fix as the Growler (?)), and lastly, external weapon pod. Note: the IRST tank/pod is apparently already available.
