Oh hey, I think you may be the first to report that an info request was made for a January submission! And 56 days from submission to inquiry isn't too shabby either, maybe we will see processing times trend down again.
As for your question, it seems that often there can be five or six days between info request and the eventual issuance of the nomination; in this forum we've occasionally seen cases where it took a bit longer, like twelve days or so. Maybe check your spam folder again just to be sure the officer did not email you. Other than that, if previous timelines are any indication, I think you should be seeing progress on your application soon.
