PSoC5 family has an extraordinary amount of internal hardware (UDBs, ADCs OpAmps etc) and a rather extensive routing scheme, but no BLE. This is not the case for a member of the PSoC4 family, but it still contains a lot of interrnal hardware. Creating a remote control or an interface for a remotely controlled device can easily be done using a PSoC4. Having the additional feature of a Bluetooth interface as the BLE versions have got will reduce the package count a lot.
So this might not be a question of PSoC5 or 4BLE, get hands on a BLE Pioneer kit and see what it can perform.
