  Recently several papers extracted $|V_{cb}|$ using the Belle measurement of
the exclusive $\bar B \to D^* \ell\bar\nu$ unfolded differential decay rates,
available for the first time. Depending on the theoretical inputs, some of the
fits yield higher $|V_{cb}|$ values, compatible with those from inclusive
semileptonic $B$ decays. Since these four fits use mostly the same data, if
their correlations were close to 100\%, the tension between them would be over
$5\sigma$. We determine the correlations, find that the tension between the
results is less than $3\sigma$, and explore what might lead to improving the
consistency of the fits. We find that fits that yield the higher values of
$|V_{cb}|$, also suggest large violations of heavy quark symmetry. These fits
are also in tension with preliminary lattice QCD data on the form factors.
Without additional experimental data or lattice QCD input, there are no set of
assumptions under which the tension between exclusive and inclusive
determinations of $|V_{cb}|$ can be considered resolved.
