If you like your go-anywhere SUVs on the large side, we’ve got good news and bad news for you. On the positive side, Lexus has confirmed that it will debut a refreshed version of the LX 570 SUV in Detroit.

The bad news, though, is that the LX and the Toyota Land Cruiser will take a year off in 2012, victims of declining sales or excess inventory in the U.S. pipeline, though the Land Cruiser has seen the worst of it. Through November, Lexus has sold 2,843 LX models, while Toyota had managed to move just 1,497 Land Cruisers.

What that means for the future of the Land Cruiser remains uncertain. At a starting price of nearly $70,000, the Land Cruiser is a tough sell even in a healthy economy, especially when the more prestigious Lexus version starts at just $10k more.

Details on the changes to the LX are lacking, but it’s reasonable to expect some exterior styling tweaks and improvements in fuel economy, since the current Lexus LX 570 only delivers 12 mpg city and 18 mpg highway. Even the Cadillac Escalade does better than that in the city, and Infiniti’s rival QX56 bests the Lexus LX in both city and highway fuel economy.

We’ll give you more updates on the new Lexus LX and the fate of the Toyota Land Cruiser as part of our comprehensive Detroit Auto Show coverage.
