I got nothing, Falls.

I do think that Toyota will stick with body-on-frame design with solid rear axle...they have to...their next gen Land Cruiser/LX will have these features. Thus, Toyota still believes that it can beat other competitors while still keeping these off-roading design features.
I doubt that they will stick in a 5.7L V8...it is just too big to fit in a midsize SUV...the Tundra is freaking huge, as is the next gen LX/Land Cruiser. And i believe that the Tundra is STILL available with the 4.7L V8, which means that Toyota is not giving up that engine anytime soon. Therefore, the 4.7L V8 may still be here when the 4runner gets redesigned. And the current 4.7L V8 VVTi makes good power...on par with it's class of midsize truck engines.
As for USA vs. Japan, i prefer Japan made...but not a big deal (aka deal breaker). Definitely, i would NOT buy a 1st year model, no matter where it's made. Just something to ponder...the '07 Camry V6 and ES350 have tranny issues, while the IS350/GS do not. The former two are made in USA, while the latter two are made in Japan. Coincidence? Bad luck with supplier?
It's hard to change the mindset of a culture with protocols, even strict protocols. Japanese auto workers traditionally grow up in a culture of self-responsibility and pride in what they make...remember those movies where the Japanese would impell themselves on their sword because they failed?? Toyota (and Honda) manufacturing protocols enhance these virtues. These protocols don't make them, they enhance/encourage them. So, although i think that these protocols can be incorporated successfully in USA, i do not think that you will have the EXACT equal in results. Of course, Japanese people (sons/daughters of those legendary workers) nowadays are very Western-minded and no better than us Americans in terms of their traditional values and virtues. Therefore, i think that the gap between Japanese made and American made are closing rapidly with each generation. As more and more people adapt Toyota ways of manufacturing, you will see the gap close even further.
BTW, my hospital administration is adapting Toyota's ideas in running the hospital...not sure if it's good or bad yet.
BTW #2, i would keep an eye on those Koreans...they are making a fast run to the top. I doubt that they will make anything to compete with 4runners and other off-roaders, but they are going after the breat-n-butter sections (crossover SUVs, Camrys/Avalon section, econobox, & midsize luxury sedans).
