I have just seen this but I guess this relates only to current, new and future editions of 3DS Max. If one has an older copy of Max, I guess one is relatively safe with the current Max Exporters from N3V (up to Max 2012 I think). As I have 3DS Max 2009 (woohoo), I also guess I should be relative future proof for some time with 3DS Max, unless someone else tells me different.
We're undecided at this point whether the existing exporters will fill our requirements for TANE. You will still be able to use them to create TS12 content, and then import that content into TANE, but there's no guarantee that you'll be able to create native TANE content using the old exporters.
