All three receivers support both side-by-side and top-and-bottom 3D formats, and will have added 3D Blu-ray support thanks to a firmware update coming later this year.  They all sport four HDMI inputs, but only the 467 and 567 can decode Dolby TrueHD and DTS-HD Master Audio.  

Each of the new receivers also handle 36-bit Deep Color, x.v.Color and 24Hz refresh rates.  They've even got Lip-Sync compensation, which automatically eliminates audio sync issues.  The 467 and 567 also offer the Yamaha Parametric room Acoustic Optimizer (YPAO) which analyzes your room and customizes audio settings to suit your needs.
