  After the recent experimental results on neutrino oscillations, some shape starts to emerge from the puzzle. However, the situation is still far from being clarified. First of all, accommodating all experimental results in a single and simple framework is not possible, and the possibility of sterile neutrinos entering the oscillation process has not been ruled out. Moreover, new questions arise that the presently-available data, nor those that will be available in a near future, will be able to answer. In this paper some of these problems will be discussed, as well as the experimental guidelines for their clarification.
