Have you been chomping at the bit to figure out when you'll actually be receiving that Nexus 4 or Nexus 10 from the Play Store that you're definitely going to buy? Well, here's your answer, straight from Google: orders will begin for both on the 13th, and those orders will start shipping the same day. No pre-orders will be taken. So, if you go for overnight shipping, you could theoretically have sweet Nexus goodness the very next day - November 14th.
The exact time orders will be starting wasn't provided to us (we wouldn't bet on midnight - probably more like early morning), so there's still some uncertainty, but it'll obviously be early enough in the day for some orders to actually ship.
