The search for antideuterons in cosmic rays has been proposed as a promising channel for dark matter indirect detection, especially for relic particles with a low or intermediate mass. With the current operational phase of AMS-02 and the ongoing development of a future dedicated experiment, GAPS, there are exciting prospects for a dark matter detection in the near future. The talk analyzes the current understanding of cosmic antideuterons, re-assessing the impact of crucial elements of the theoretical determination of the signal: the modeling of antideuterons formation (coalescence process), transport in the Galaxy, transport in the heliosphere and finally impact on the antideuteron signal of the PAMELA bounds on the correlated antiproton signal. It will be shown that prospects of unambiguous detection of up to about 15 events in GAPS LDB+ and AMS-02 missions are found, depending on the dark matter mass, annihilation rate and production channel from one side, and on the coalescence process, galactic and solar propagation parameters on the other.
