Autodesk will not release nothing for public or private use. There´s a lot of Patents on XSI that they can "replicate" now inside their other Apps (I will not bet a single dollar on this). But They can. Before the XSI EOL they "can´t" replicate stuff (redundancy), cause it will accelerate the death of their own software, but now, they can.
Nowadays Adesk products entered on slow development...
As we can see,coders, almost alone can bring up to the market an almost fully featured Render (Corona). Other guys, like JokerMartini, Clovis Gay, and the ThinkBox Guys shows that Max´s Core could be bad (as everyone keep yelling) , but not THAT Bad, cause they can (and show) Incredibly fast tools made by small teams of coders, even using MaxScript, with an unbelivable Speed, running on the same, "bad", Max´s core.
How can 3dsmax´s core to be worst for Autodesk native tools than for those guys around the world ? Hell no.
