It is argued that recent developments point to the existence of an AdS3 x S2 x T5 holographic dual for the 2D CFT living on the worldsheet of N coincident heterotic strings in a T5 compactification, which can in turn be described by an exact worldsheet CFT. A supergravity analysis is shown to imply that the global supergroup is Osp(4^*|4), with 16 supercharges and an affine extension given, surprisingly, by a nonlinear N=8 2D superconformal algebra. Possible supergroups with 16 supercharges are also found to match the expected symmetries for Tn compactification with 0<=n<=7.
