Microsoft might have closed the last chapter of Nokia's Lumia book, but the story is far from over, especially with many unanswered questions left hanging. One of those pertain to the supposed Lumia 1020 successor, a smartphone codenamed "McLaren". Aside from continuing the 1020's photography lineage, this McLaren was supposed to also bear a "3D Touch" interface. However, it was rumored to have been axed mid year and vanished without a trace. That is, until this RM-1052 prototype surfaced in China, which could very well be that stillborn smartphone.
