For most of this year, Google has been rumored to be working with both LG and Huawei on two new Nexus smartphones - a new Nexus 6 phablet made by the Chinese company, and a successor to the Nexus 5 from 2013 by the Koreans. The two handsets have been leaking so much lately that their existence is as good as confirmed. We've already heard from a few places that the big unveiling of the two new Nexus-branded devices will occur on September 29. But when will you be able to order one?
