Don't rush to buy redmi note 3 yet. Wait abit and see see. Some things for you to consider first. First, it is not full metal. Top and bottom at the back is plastic, the integration between the plastic and metal quite obvious. Second, 4000mah sounds impressive but no one knows the actual power usage of the fingerprint reader yet. For all you know the extra 1000mah juice difference from the redmi note 2 is to power the fingerprint reader. Thirdly, issue of heat. Currently, for redmi note 2, sometimes the heat gets unbearable and holding the back of the phone can be quite a pain but since it is plastic,the impact vs metal not so bad. Metal redmi note 3 probably cool down faster but maybe also conduct heat faster. Last point, if want to get, get the higher end one, 3gb and 32gb rom can last you a long time.
