One of our previously reliable sources indicated that the Nexus 4 could indeed be back in stock today in the Play Store (U.S., not sure about others).

9am PST is the word currently.

We decided not to post it on the site in case it ends up slipping, but given http://www.androidpolice.com/2013/01/28/today-must-be-nexus-day-all-sold-out-nexus-play-store-pages-now-say-temporarily-out-of-stock, we're inclined to put the probability of it actually happening somewhere around 80%.
