If the rumors and leaks are correct, we might be seeing three different trackers from Fitbit. They are Fitbit Surge, Fitbit Charge and Fibit ChargeHR. They are similar except that the Surge has GPS and heart rate monitor (PurePulse) and ChargeHR has a Heart Rate monitor, while Fitbit Charge remains the basic model.
Not sure if these images are real but they seems legit to me. It has been a long time since the last update from Fibit. The previous Fitbit Force was pulled from the market due to some complains on skin allergies on some users after using it. It did not even make it to Singapore.
Anyway, check out this brochure that shows the Fitbit Charge and Fitbit ChargeHR.

The Fitbit Surge might cost you US$250 when launched. Hopefully, Singapore can get three of them since my Fitbit Flex just went dead recently.
