Sources speaking to ZDNet and Thurott.com have dropped the codename for a major overhaul to Microsoft’s Surface Pro: ‘Carmel’. According to ZDNet’s Mary Jo Foley, the product won’t launch until mid-2019 but will be heavily redesigned.

Both reports also reference codenames for the previously reported upcoming Xbox and HoloLens sequels, known internally as ‘Scarlett’ and Sydney, respectively.
