  We emphasize a that since GRB970508 released an energy of Q_g~10^{51} \Omega
ergs in soft gamma rays alone, the actual energy of the e^+e^- p FB driving the
blast wave could be considerably higher than this value, Q_{FB} >Q_g. For
reasonably large values of \Omega, as is probably suggested by the radio
observations, the value of Q_{FB} ~ 5.10^{51}~t_m^3~n_1 erg, for GRB970508;
here t_m is the epoch in months when the associated radio-blastwave degrades to
become mildly relativistic. We discuss that it is unlikely that this energy,
Q_{FB}~sim 10^{53}erg was liberated by the central engine by a direct
electromagnetic mode. On the other hand, as conceived by several previous
authors and as is suggested by supernova theories, their FB driving the blast
wave is likely to be preceded by a much stronger neutrino burst: \nu + anti
\nu- e^+ +e^-. Although, the efficiency for pair production by this latter
route is usually found to be as low as ~.001, we point out that for very high
values of neutrino energy release Q_\nu >Q_{FB}, it is possible that, its value
increses substantially. By considering that, the value of $Q_{FB}$ for such
GRBs is indeed ~sim 10^{53} erg, we envisage that the energy of the actual
neutrino burst/wind could be as high as ~ 10^{54-55} erg. This energy might be
had from general relativistic collapse of a massive stellar core having INITIAL
gravitational mass, say, M_i~ few~M_sun to a stage having a potential well much
deeper than what is present on a canonican neutron star surface. Accordingly,
we predict that the new generation large nu elescopes may detect neutrino burst
of energy ~10^{54-55} ergs, with neutrino energies touching ~ 1 GeV, in
coincidence with GRBs.
