Maya scenes are not backward compatible as well, but the funny thing is
that if you save a scene as Maya ascii, you can change the version
number in a text editor, 9 out of 10 times the scene loads without any
problem in any previous version. I suspect its more a business decision
to boost sales then anything else.
I bet if you knew what to change in a SI 2013 scene, it would load just
fine in 2012.

I am sure you are right. For some reason I thought file formats didn't
necessarily change every release but I think I was mixing up service
packs/SAP with annual releases. For instance I can load SI2012SAP scenes in
SI2012SP1.
Sorry for the confusion -

This is expected with every new version.
Do you usually load scenes into older versions? I'm surprised it works, it
never does for me.

Just a heads up in case it affects other people, I was just trying to check
some differences in RTShader behavior in SI2012SAP (and there are
differences fwiw) and was greeted with the following error when trying to
load the scene:
---------------------------
Autodesk(r) Softimage(r)
---------------------------
You are trying to load a scene with an unsupported version.
This software supports scenes from version 108 to 1000
Actual scene version: 1000
Please try to load it from version: 1100
---------------------------
OK
---------------------------
I don't think I used any new features in the scene, but thought maybe I did
without realizing it so I tried again saving an empty scene in 2013 and it
wouldn't load in 2012SAP either. Not sure if this is expected with every new
version of SI but I never noticed this happening before so I thought I'd
mention it in case it helps someone who needs to remain compatible.
