In type A, the q,t-Fuss-Catalan numbers can be defined as a bigraded Hilbert series of a module associated to the symmetric group. We generalize this construction to (finite) complex reflection groups, investigate some first examples and exhibit nice conjectured algebraic and combinatorial properties of these polynomials in q and t.
