  "abstract": "We investigate the enhancement in the D^0\\bar{D}^0\\pi^0 final state with the mass M=3875.2\\pm 0.7^{+0.3}_{-1.6}\\pm 0.8 MeV found recently by the Belle Collaboration in the B\\to K D^0\\bar{D}^0\\pi^0 decay and test the possibility that this is yet another manifestation of the well-established resonance X(3872). We perform a combined Flatte analysis of the data for the D^0\\bar{D}^0\\pi^0 mode, and for the \\pi^+\\pi^- J/\\psi mode of the X(3872). Only if the X(3872) is a virtual state in the D^0\\bar{D}^{*0} channel, the data on the new enhancement comply with those on the X(3872). In our fits, the mass distribution in the D^0\\bar{D}^{*0} mode exhibits a peak at 2-3 MeV above the D^0\\bar{D}^{*0} threshold, with a distinctive non-Breit-Wigner shape.",
