I think that is an absolutely wonderful decision. I wish I was of student age (and spoke Polish!) to avail myself of it, and the associated maths courses.
I think mathematicians, and more particularly, users of maths, have a range of styles of thought, and the every concrete approach, which Mathematica encourages, would certainly have appealed to me.
To give a specific example, I remember trying to learn about group theory. For a long time, groups seemed somehow vague to me. I learned the axioms of what counted as a group, and thought "Yeah well  so what!". I learned (or tried to learn) assorted other definitions, such as "normal subgroup", and of course, I looked at various tiny examples of groups. However, what I really needed was software which would let me make examples that were big enough to begin to see why all those definitions were any use  software that let me explore. I am the sort of person who finds it hard to learn something that doesn't seem any use  even if I know that everyone says it really will be useful once I get to understand it!
As to the issue of alternative CAS software, I did chemistry, and nobody worried about the fact that all our NMR machines were Varian, or that the infra red machines were made by Perkin Elmer, or that we learned to program the type of computer owned by the university  a technical university course inevitably focuses its students on certain products.
You say the focus will be on graphics rather than symbolic computation, but I must say, I think symbolic computation is the more exciting part  because it opens up entirely new possibilities.
Take symbolic integration as an example. I know there are those who would say students should be told to solve all their integrals with Mathematica (and take a calculator to add their bills when they shop) but I am not thinking that way. It is easy to make a construct in Mathematica that displays like an integral, but doesn't evaluate. Using this, students could explore strategies such as change of variable  simply using pattern replacement and simplification. Mathematica would be contributing no skills that the students didn't already know  simply adding some muscle to help explore more substantial problems.
I wish you success!
