But both engine can't mix , all is different :
language, Engine access and core is different.
All pipeline , all architecture is different.

But Conitect could buy it and make A9 from this new base.
It could be some AAA features engine with top notch tools and editors indeed.

But i don't think of that , and im' pretty sure A9 will be only
A8 following path.
Like A8 that is just A7 continuing developement and improvment.
