This map shows that there is no FX planned for the future, not even in 2015. So it seems that the reports of FX-9000 being the end of the FX line were true. I guess this sucks for people who liked hexa- and octo-cores, but it's possible that we'll see hexacore APU's in the future on FM2+.
Interesting to note that the 65W max TDP for Carrizo is confirmed, as is Carrizo having Excavator-based x86 CPU cores and still being on FM2+, so FM2+ isn't dead after Kaveri as some have speculated.
Elsewhere I have seen mentions of a future APU codenamed "Basilisk", though no info is revealed on it yet. I can only speculate that it will succeed Carrizo, quite possibly being Excavator-based but offering DDR4 support. This would probably be the opening for the FM3 platform.
