Long standing problem of the nature of the phase transitions in weakly Disordered Ising-like statistical systems [1] is considered from the point of view of the recent developments in the replica method [2]. In particular, non-perturbative [3] and non-selfaveraging [4] phenomena in the critical point are considered,as well as the possibility of the universal probability distribution function for non-selfaveraging free energy critical fluctuations is discussed [5].
