The Surface Pro 4 has yet to turn up but rumors already formed a promising visage. With the rich enumeration made available after countless conjectures and a dash of wishful thinking, it becomes all the more fascinating to figure out how Microsoft will craft the highly-anticipated refresh of the tablet laptop-hybrid lineup. But in the event the speculations come about, this is how a battle between the immediate kinfolk will look like. 

The Surface Pro 3 already has an impressive selection of hardware and specs. As far as build is concerned, Microsoft is projected to make the upcoming device even better. Rumors suggest that the Surface Pro 4 will come in two sizes. While the Surface Pro 3 sports a 12-inch Full HD display with a 2160 x 1440 pixel resolution, the Surface Pro 4 may go for an 8-inch screen variant and a bigger one, which will be about 13 to 14 inches in size. Should this come to pass, the newer hybrid will undoubtedly score more sales for the company. The smaller model is set to compete with Apple and Android tablets in the turf while the larger one will be a prospective hit in the business section of the market. 

Naturally, a newer version of a device is expected to go with upgraded insides. Many imagine that Surface Pro 4 will get a more powerful processor, which will top Pro 3's 4th generation Intel Core processors (i3, i5 and i7 clocked at 1.50 GHz, 1.90 GHz and 1.70 GHz, respectively). An increase in RAM may also be set. Pro 3 currently has an 8 GB RAM in the bag. 

As many lie in wait for the arrival of the Surface Pro 4, many believe that Windows 10 (which is in heavy testing at the moment) will tag along. Surface Pro 3 runs Windows 8.1 Pro and the Surface Pro 4 is touted to be the first Microsoft device to ever have the company's newest software onboard. But this may be a double-edged sword. Fresh operating systems are usually loaded with bugs and irks at the dawn of their rollout. Windows 10 has a higher chance of not being spared of this curse. Nevertheless, the software is expected to bring loads of fixes and improvements to Windows 8, which was heavily criticized. This might be a good thing after all. 

Pricing is still hard to figure out at the moment but Design & Trend, citing The Telegraph as source, bets on a price range of $1,000 to $2,000 for the newer Surface tablet-laptop hybrid. Meanwhile, Surface Pro 3 has a starting price of $799. With regards to the release date for the Surface Pro 4, it is predicted to be launched by mid-2015.
