One thing that seems to be apparent with the Encore 2 is a downgrade in the Wi-Fi module. The original was capable of dual-band operation, while the Encore 2 looks like it's limited to operating only on the 2.4GHz band, with the specs listing the Wi-Fi module as being capable of only 802.11b/g/n, rather than a/b/g/n. Bluetooth is version 4.0.
We'll know more about the spec, and will report on its battery life and weight, once we get our hands on it for a full review.
