The Raspberry Pi Foundation is not holding back. Since the original Raspberry Pi B launched four years ago, there has been a steady stream of new devices and upgrades: The much improved Raspberry Pi 2 came out two years ago, and it was just before Christmas that the tiny form-factor Pi Zero launched. Today, they've announced another upgrade in the form of Raspberry Pi 3 B, also selling for $35.
Apart from an upgrade to a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU, the most exiting news is the integrated 802.11n wireless LAN and Bluetooth 4.1. Ideally, it means that no other external devices are needed, assuming that a Bluetooth keyboard works (sometimes they can be flaky).
This will likely be a hit, so expect to wait for some time for stocks to fill up with the different retailers. And of course, the stated price might not be obtainable if buying locally.
