The three images that were obtained through their video on the Geneva 2012 previews both current and future Lexus models. Although the cars are heavily shadowed, the dimly lit fascia is enough to give us a hint of what car it is. The new spindle gille design which debuted in the CT200h can also be seen on the recently launched GS350 and the LX570 is also present on all 3 future models which we assume to be the 2013 LS, ES, and the 2014 IS.
The 2013 LS(shown above) and ES(shown below) sports a mesh type grille, which may indicate that an 'F' variant will be made available once it is released. The 2013 LS is expected to debut later this year at the L.A. Auto Show, while the 2013 ES will be showcased next month at the New York auto show.
Lastly, the photo below appears to be the next-generation IS, looks to be tamer due to the grille which although sporting the same spindle design just like every other Lexus models, the horizontal chrome strips gives it a more premium and luxurious look.
