Gadget lovers planning to buy some on the "Black Friday" Sale day can hold for a couple of months to experience three best tablets launching in 2017. Three tablets listed here run on three widely used operating systems - Android, iOS and Windows.

Although, these three tablets have best specifications might not fit in a small budget, as they all are big shots of the tech market. The 2017 year is expected to welcome Google Nexus 7, iPad Pro 2 and Surface Pro 5.

Google's Nexus 7 may be named as Pixel 7 as there are too many rumors around this tablet. But, according to the latest Tweet by Evan Blass, there were many hopes aroused in Android tablet lovers. The tweet says: "Google's Huawei-built 7in tablet was on track for release before the end of the year." As we are close to the year's end it must be expected early next year.

All the online sources that allegedly quote specifications of Google Nexus 7 are Android 7.1 Nougat OS, 7in Quad-HD (2560x1440) pressure-sensitive display, Qualcomm Snapdragon 820 processor, Adreno 530 GPU, 4GB RAM, 64GB storage, MicroSD support up to 2TB and 13Mp rear camera.

According to PC Advisor, the tablet running on Windows operating system Microsoft Surface Pro 5 is expected mid next year, as Surface Pro 4 was launched in last October. Another reason for its delay can be the delay in releasing new Windows 10 update.

A tweet from a developer shows a wall in Microsoft's office 88 with Surface device with 2016 date and three devices with 2017 date. The suggested specifications of Surface Pro 5 include a 2K screen in the basic model and a 4K screen model.

Surface Pro 5 is speculated to get the first USB-C port rather than the USB 3.0 port on the Pro 4. Microsoft will also upgrade cameras, Wi-Fi and Bluetooth. The price would be more than Surface Pro, which costs $950.

As previously reported, Apple's planning to launch 3 tablets under the iPad Pro 2 name with different display sizes. iPad Pro 2 9.7-inch, 10.5-inch, and 12.9-inch are reported to be launched early next year. Suggested specifications of iPad Pro 2 include A11 chipset and 3 GB of RAM. Expected prices of iPad Pro 2 of 32GB is $799, 128GB is $949 and 256GB is $1099
