Well, in fact A8 would need a remake total fo some fundations :
Like a totally new World editor with totally new graphics ,lot faster, cutomizable interface , and all tools integradted like terrain editor etc ...

For example all MED functionnalities should be integrated in WED directly.
And panels for managing physics like in Gamecore or Unity should be here in 2009 ?
Well A8 would need an improvment on workflow an world editor !
