Having launched the Pixel and Pixel XL last year in October, Google will most likely do the same with this year's iteration, the Pixel 2. While earlier reports stated that the launch would most likely happen on 5 October, a report by Droid Life might be very close to confirming the date as 4 October instead.
The report shows an image of a billboard which was sent to the publication from Boston. It clearly reveals the caption 'Ask more of your phone' along with the Google 'G' branding below followed by the date. According to the report, there are arguments that the billboard may be referring to something else, but given that the Pixel launched at around the same time last year and that it is indeed referring to a phone, a Pixel 2 launch event is very likely.
Based on what we know so far, the new Pixel devices will be made by two different OEMs, one being HTC for the Pixel 2 and the other being LG for the Pixel XL 2. While many expect the Qualcomm Snapdragon 836 to feature for the first time on the new Pixel devices, a previous report states that Google might have hit a roadblock there and that it will have to settle for the Snapdragon 835. The 835 is no slouch, so that's certainly not a bad thing. Last year's Pixel devices released at the tail end of the 821 chipsets life, but the delay of the 835 this year means that an October launch will not be as bad.
The display on the Google Pixel 2 XL is expected to come in at 5.99-inches while sporting a bezel-less design. The regular Pixel 2 is expected to follow a design more similar to its predecessor while sporting a smaller, 4.97-inch OLED display, compared to the Pixel XL 2.
On the software front, both the devices are expected to run Android Oreo out of the box with a stock build. The 3.5 mm headphone jack is also supposed to get the axe this year with Google opting for a single USB-C port on the phone.
