Will there be no Symbian Carla?

According to the latest information, the Symbian system will no longer receive a major update.

Unfortunately, we have bad news for Symbian device owners: Mattia Fiorin, Nokia’s head of product marketing, said Symbian Carla is not included in the current plans. Instead of a large-scale upgrade, Belle will receive a feature called Feature Pack 1. Of course, the knowledge of the system will still expand, but it will certainly not be nearly as big a milestone as Carla would have been. According to the information, the Finns are even planning to release an FP2 update, and then Belle will no longer receive any more updates.
