For the Google Nexus 8, rumors have been flying around that it will be coming from Huawei this time around. The bad news is that LG has been rumored for almost all of the other models as well, so it remains to be seen at this time since there are no confirmation reports from Google, Huawei or anyone else.
Other rumors that have to do with the new Google Nexus 8 is that it will be coming along with the brand new Nexus smartphone. That smartphone, the LG Nexus 5 2015 is expected to be released at the end of next month as well.
At this time, and it makes sense, the Google Nexus 8 is expected to be announced at the same time. This does not mean that the Google Nexus 8 will be available for purchase on that date, but it will be announced and will likely be on store shelves by the time the busy holiday shopping season arrives in November.
