So how many are looking to "upgrade" to the new GX550? Or even an LX600?

Both would be well outside my budget. When the GX 550 hits the showroom, I will check it out.

However, unless they offer a two-row GX trim, I'll never regret going the 4Runner route.

I won't trade in my 4Runner for one, but I may consider a 550 if something were to happen to it.

Honestly though, if I had to replace it, I'd probably go with a new Tacoma Trailhunter.

470 owner here,
I am considering between GX460 and GX550, so will be watching this thread.

I don't think I will be able to buy a GX550 due to the demand as I don't want to pay markup for it.

The GX460 will be pretty much care free.

I have not really looked into GX550 engine setup. Some say it's a detuned LX600 engine. But if it's two turbos attached to the cylinder head and twin liquid intercooler (lots more coolant and hoses), plus maybe plastic valve cover, then I could see it will be significant more trouble to maintain compared to a 4Runner V6 or GX V8 engine. That's without discussing the Hybrid system which the battery will make the trunk floor high, no 3rd row as common drawbacks of Hybrid.

Looking deeper into the GX550, I really doubt it fits our needs as well as the old GX460 we have. No idea what the GX600 is going to be like. But so far I'm not impressed with what I see.

I admit when I am wrong. After test driving a 4Runner Limited and a GX460 on the same exact route that had varying road conditions. The GX was better in every way and the sale price I am getting makes it close in price to the Runner Limited and Pro.

I think I will never regret buying the Lexus...

Yeah, the Lexus salesman wanted to gauge my interest in getting on their still short waitlist for the new GX550 and I told him I'd rather go for the bulletproof Prado and call it a day.
