Apple have done an awesome job on iOS7 IMHO (although people seems to be a bit polarised on that). Apple have now updated iCloud to look more like the iOS7 style. Mavericks is now the odd one out. It sounds strange to me that everything apple would be updated to a new UI apart from the OS for a whole year until Mavericks successor next summer. Any chance of a switcheroo at the last minute by Apple do you think? Suddenly Mavericks having a new iOS7 style overhaul just before release? I'm thinking less of a last minute rush by apple and more something that they were planning and have been secretly working on all along.
