The new ones from Baselworld look pretty similar, only the dial seems not be as shiny. I tried on a LM at the local Omega Boutique some time ago and I have to say it looks pretty stunning in the flesh! I'm not too sure about the dial for daily use, though. It's really, really blingy and very similar to the GMTIIC's bezel.
Here's a bad picture from Basel, the watch pictured supposedly is the new 42mm version with 8500 caliber . Size wise pretty similar, only about one mm thicker, 15,7mm if I remember correctly and with display back (the 8500 is beautiful so I won't say anything about tool watches ).
