Hi Tamer, The old .osg format has been officially deprecated but we'll be maintaining the format for the next OSG version and likely beyond. Even when we eventually retire the .osg format support for the core OSG it will still be possible to provide support via an external plugin.
The replacement for .osg is via general purpose serializers that enable ascii, binary and XML OSG file formats and is extensible so you'll be able to add your own serializers for your own custom data structures and be able to use any of the .osgt, .osgb or .osgx formats. Have a look at the src/osgWrappers/serializers for examples for how to provide the serializers. Robert.
