Unless Wibree is going to be yet another wireless protocol incorporated into a cellphone along with Bluetooth and WiFi, it was implemented wrong if it intends to be a replacement for Bluetooth.
To be a replacement for Bluetooth, the range aspects of Wibree is far too short for practical applications. And quite frankly using anything less than Class 1 Bluetooth transcievers in cellphones is a losing battle as well.
As Bluetooth finally gains a foothold in the real world, it has become increasingly apparant that the short range Class 2 Bluetooth has no functionality in practical applications. Nearly every application that is come up with uses and relies upon the Class 1 specification for the extended range, and antenna matching has become an industry buzzword with Bluetooth devices. There is actually a growing shortage of Class 1 devices as fab plants are ramping up for higher production, and Class 2 devices are being stockpiled.
The general software and stack updates have made Bluetooth much more desireable shortening the connection times to a fraction of a second in many cases and allowing even higher data transfer rates. Next to WiFi, Bluetooth is truly the data moving technology out there.
With the advent of Wibree, it is a technology developed far too late in the game, with a distance that is far too short to be usable or desireable by either developers or companies. Couple that with the inability to multi-source any stand-alone Wibree devices with serial connections, larger companies will never buy into it.
The only saving grace for this technology is that it may be very suitable for financial transactions. If banks buy into this technology, rather than going with self-powered RFID plasticized strips, then there may be some future for Wibree. Otherwise it would have been better to figure out how to reduce the cost on the smartphone devices and to open a direct to retail sales channel, rather than rely upon the quickly dying channel markets.
