  Recently a broad class of superconformal inflationary models was found
leading to a universal observational prediction $n_s=1-2/N$ and $r=12/N^2$.
Here we generalize this class of models by introducing a parameter $\alpha$
inversely proportional to the curvature of the inflaton Kahler manifold. In the
small curvature (large $\alpha$) limit, the observational predictions of this
class of models coincide with the predictions of generic chaotic inflation
models. However, for sufficiently large curvature (small $\alpha$), the
predictions converge to the universal attractor regime with $n_s=1-2/N$ and
$r=12\alpha/N^2$, which corresponds to the part of the $n_s-r$ plane favored by
the Planck data.
