Would you want the new 7.3 V8 in the F150?

Well as I understand it the new port/direct FI systems are a result of driveability concerns and power delivery. It was always noticed on test stands by most makers that DI with the right controls makes the combustion faster and more efficient - but there were always issues around it with PCV contamination or High RPM leanout or high load predetonation - and other issues. So a few companies have experimented with Port and DI for gas engines and it does fix a number of issues with very minimal change. I mean port injectors are cheap in comparison - making holes in the plastic intake for them also cheap - and it smooths out the power delivery and in some cases leads to better over all efficiency. It supposedly is a relatively new development. Meanwhile I'll say this - lightly surprised you don't see more dual spark plug use also.
once again you might should get out more. There are a number of 2v engines making over 700 hp without huffers attached to them. No they didn't leave the factory that way because factory built cars rarely have high lobe cams, or headers - since noise requirements and often longevity requirements of corporate policy remove those features. To that end what factory engine makes 650Hp or so without some huffer attached. I'm at a loss other than I guess one of the ferrari v12's.
However - there are a number of LS7's that with cams and headers knock over 650HP with ease. Hell Some stock LS7 vettes dyno at 580 factory stock with light tuning.
In the case of this engine it's goal is low to mid range torque as it's purpose built for a HD truck chassis.
Curious this is the second time I've heard something like this but I thought it was more a case of including Air ride as an option.

Chevy 632 comes to mind, easily upwards of 950 HP on pump gas and no blower, just a big fat carb and hot spark.

Thats too big of a motor for a 1/2 ton imo

I'd love one! The torque of the 3.5 without the angry vacuum cleaner noises and turbo lag.
That said, I figure there's a 1% chance that this will ever show up in a F-150 and if it does it'll be a SVT special edition at $80,000.

Where did you read/hear that? I do know that the height of the Superduty does turn people away to the other two. Those in the RV world tend to be older and less agile, and getting into one of these later gen SD trucks can be a pain, especially if there are no running boards.
Also keep in mind that a 1/2 ton truck is rated 8500 and below GVWR, which limits how much payload it can actually carry, though it does appear that your idea would fall within that class, but the CAFE would be destroyed.

Ford engineers purpose built the 7.3 to be mated to the HD 10 speed to achieve optimum stoichiometric efficiency in heavy duty trucks that are constantly over 10,000# GVW. Pushrod motor with port injection that runs at low RPM. Probably not much fun in an unloaded every day driver.

I would love to have that engine on a F150 but I think if they do offer that on a F150 "XD", the price will be really high, otherwise it will kill the 3.5 Eco...
The dealer I bought mine from have 3/4 of the trucks on the lot equipped with the 5L V8 and I guess that if the 7.3L is offered as an option at the 3.5L eco option price, the 3.5L is done, at least in my region....

And that's exactly why it won't go anywhere else. If Ford only uses it in HD applications, which is exactly what it was designed for, there will be little or no aftermarket interest. And if you want a high output bigblock Ford for other applications, those options already exist with plenty of aftermarket support.

no there's no aftermarket interest in the HD truck market. NOne at all.
There will be tuners for this the day it's on the dealer lot.
There will be headers for this within the first year and probably a cam kit or 2. Call it a hunch
