We present predictions for the value of the cross section ratio $\sigma(e^+p\to e^+p)/\sigma(e^-p \to e^-p)$, determined from our fit of the elastic $ep$cross section and polarization data. In this fit we took into account thephenomenological two-photon exchange dispersive correction.  The cross section ratios which are expected to be measured by the VEPP-3experiment are computed. The kinematical region which will be covered by theE04-116 JLab experiment is also considered. It is shown that for bothexperiments the predicted cross section ratios deviate from unity within morethan $3\sigma$.
