Indeed. C\C++ still makes the most sense for a large scale commercial project due to it (still) being the industry standard and it being extremely portable. Pretty much every game on the shelves is written with is.
I use Blitz because I'm more interested in game design than struggling with Windows. So I can get on with making the game very quickly. Blitz isn't very portable (certainly with regards to consoles) but porting the code to C is very easy so it's not the end of the world.
If I had a nice looking PC game written Blitz (3d or Max) I wouldn't expect any objection from publishers at all. And if they wanted to port to a console porting over to C is easy enough.
