The problem is considered of existence of flavor multiplets consisting of multi-quark baryons. We have argued that the S-matrix should have poles, at least Regge ones, with any quantum numbers, including exotic. This is a novel argument for possible a proof, yet there are no theoretical arguments to forbid exotics. Then we apply the partial-wave analysis (PWA) with addressing mainly to the non-strange exotic members of the anti-decuplet or even of higher multiplets. It suggested new N(1680) as a possible partner of Theta+.
