Then no one would make anything new. "too low level" is an ugly way to put it, though I can understand if you want some
additional higher level options. HLSL with A7 (and especially with the extra functions from default.fx) is easier than Lite-C or C-Script, and indie developers in particular (who often lack the resources to go for a photo-real look [too many games go for that look anyway]) could do with some uniqueness in the graphics department.
I'm stoked they're working on an in-house project, but I think the main changes will be in the editors and workflow, with a few extra functions in Lite-C, because the programming side is already very nice: concise, simple, and powerful.
