CoinX says “iMac/Mac Mini soon - iPad 100% sure”, o think this mean the iPad will be released on 31 March but not the iMac, soon can mean 3/4 months. Still no intel cpus released and it would be the first time in the last years Apple refresh the iMac before the 2 years cycle (2012-2015-2017-2019). Also the update could be the iMac...but Pro (is the same as 2017).
No, CoinX said new camera on the iPad 100%, he was refering to the new camera system that has been rumoured for a while now. The iMac/Mac Mini was a separate tweet.
