IMO ......If this article is correct .I would think they are probably pushed back because of the Earthquake disaster and the overall economic climate rather then a redesign.
They don't sell that many LC200's and 4Runners compared to their other vehicles anyways.
Japan is in turmoil right now and the reason their Prime Minister Naoto Kan resigned today .
That's the 5th one in the last 6 years. Maybe Obama will be the next to resign.....
lol
And that's how the fight got started.
Then again .......maybe they're going to put the 4.6L V8 with the 6 speed tranny and need some more time for R&D.
