Looks like they have done some changes for the latest carbon frame – especially around the seat clamp area: http://www.cube.eu/en/hard/pro-comp/reaction-gtc-race/
EDIT: looking again maybe not so much change. Probably just have no stock of older frames or maybe they have replaced a few and did update it. Either way I would consider the 2012 an upgrade and be happy with that.
I get confused by huge bike ranges like Cube has but I am guessing that will be the frame you get, pretty similar looks wise so your colour scheme will be okay which can be a pain with bikes like Cube with lots of graphics.
Probably the same frame as the two other reactions with Fox forks and different colour schemes.
Naming and shaming when a frame breaks can hurt brand strength but it also lets people know that breaks do happen which is good for making sure companies change designs and it’s also beneficial when the owners post up positive experiences from warranty claims.
