  The talk is a mini-review of the current status of the field, with emphasis
on SPS heavy ion program, now and beyond 2000 (as asked by the organizers). The
main question is, of course, whether we can convince ourselves and the
community at large that the QGP is in fact produced at SPS. We came a long way
toward the positive answer, and are definitely on strongly rising part of the
learning curve. Still, in few key directions we lack important pieces of
evidences.
