  We present a status report on the ongoing analysis of the 3D Ising model with
nearest-neighbor interactions using the Monte Carlo Renormalization Group
(MCRG) and finite size scaling (FSS) methods on $64^3$, $128^3$, and $256^3$
simple cubic lattices. Our MCRG estimates are $K_{nn}^c=0.221655(1)(1)$ and
$\nu=0.625(1)$. The FSS results for $K^c$ are consistent with those from MCRG
but the value of $\nu$ is not. Our best estimate $\eta = 0.025(6)$ covers the
spread in the MCRG and FSS values. A surprise of our calculation is the
estimate $\omega \approx 0.7$ for the correction-to-scaling exponent. We also
present results for the renormalized coupling $g_R$ along the MCRG flow and
argue that the data support the validity of hyperscaling for the 3D Ising
model.
