But at the end of the day, you are right, the complexity increases. This is why I don't see a GTDI as a bad thing. Is a TT V6 really worse than a V8 with DoD and other fancy wizardry to make it more efficient? Turbos are not complex. They are not expensive. And they are not hard to replace if one did fail. They hang off the side of the motor and have like 6 bolts at most holding them in. Almost everything DoD related is inside of the motor and is much more complex to fix.

Carbon buildup?

But at the end of the day, if people are worried about simplicity and reliability, a modern turbo diesel isnt exactly the best option here in the US.

Toyota seems to also have port fuel injection on most of their motors that have direct injection. Carbon buildup should not be an issue as they are likely using a high % of port injection at lower RPM and load.
Ford uses 100% port fuel injection on their new Ecoboost/5.0 with dual injection at the lower loads.

The 4.6 is smooth and not too different in fuel consumption as the 4.0 V6 (had this in a J120 Prado with 5speed auto). However, considering future potential issues with the 4.6; Coolant valley leak, cam tower leak, emission related AI solenoids/air pump, I'd be happy with the very reliable and relatively simple 4.0 V6 connected to the LC 8 speed auto. I'd also like to have the 2010-2013 bumper covers, the dual fuel tank option with spare on the rear door and 17" wheels (don't want over sized tires, just taller sidewalls) along with a rear diff locker.

Plus full time 4wd transfer case (I know that the 4Runner Limited has this option, but don't like the low bumper covers or 20" wheels), 150l (39.6g) fuel capacity, door mounted spare, a taller roof for more interior storage room. I do like the front end of the 4Runner but hate the low roof and I would much rather have the Prado (LexusGX) body.

Some further speculation here on Prado... nothing GX specific other than the statement
"Toyota doesn’t sell the Prado in the U.S., and it is highly unlikely to change its mind in the next generation. What the renewal of the Prado means for Americans is the possibility of the Lexus GX staying in showrooms for another generation."
https://topelectricsuv.com/news/toyo...-prado-hybrid/
"The source revealing the deferred launch talked about the design of the model. The exterior would not be similar to that of the RAV4 as represented by some auto magazine renders recently. Toyota has to maintain the design identity of the globally acclaimed off-roader, and giving it the garb of a crossover sounds illogical for this main reason. "

If the GX has a 3rd gen and the LX has the TT V6, I have a hard time seeing Toyota dropping a detuned version of the TT V6 into the GX. The LX has to be the flagship vehicle. It needs a different engine to claim that prize. Probably will be a 3.5 hybrid setup. Not concerned about reliability of the hybrid system as our 13 year old LS600hl is on the original battery. But the silky smooth and grunty V8 will be missed. V8 will always be in demand on the used market. They are also fairly easy to work on, unlike the 3.5TT in the LS500.

With the new Tundra having a base 3.5TT engine that produces more power than the 5.7, it’s unlikely the tundra will have a V8. The second engine choice will likely be a hybrid platform, as its easier to produce more power in a hybrid setup vs a V8. With this in mind, I doubt they will make an entirely new V8 just for the GX. It’s cost prohibitive as they have to go through certification.
So we’ll have a detuned 3.5TT or will get the 4.6 again (very unlikely given the corporate plan of moving away from V8s).
Or maybe the GX will be replaced by a crossover in which they can drop the 3.5 from the RX.

Just watched the latest video from Automotive Press + Kreifels....As usual a lot of speculation but they did mention that the 2023 GX engine is one of the murkier subjects for Lexus in 23; The suggested that the 2.4T could be in the cards as it offers the same power as the current V8, the 3.5TT would be a substantial upgrade in power and also make it compete a little too directly with the LX. I'm hoping for a slightly detuned 3.5TT at this point...I know that is a let down for those hoping for a V8, but I think that is almost zero chance at this point. If you still want a v8 get a 21/22 while you still can...

If they do bring a detuned engine to the GX then they it would change the naming structure
