Microsoft executives will explain their reasoning next week, but assuming the company doesn't have some game-changing secret feature squirreled away, Microsoft's attitude appears to be this: We got more right than wrong with the first Surfaces, and targeted tweaks are all the new models need to succeed.
The Surface Pro 2 is rumored to boast at least three unambiguous improvements:
--Thanks to Intel's i5 "Haswell" processor, the Surface Pro 2 should run an acceptable seven or eight hours between charges, much better than the first model's deal-breakingly poor four-hour battery life.
--With an expected 8 GB of RAM and Haswell's GPU improvements, the new Surface Pro should offer snappier performance for desktop software, Web browsing and touch apps alike.
Microsoft is also expected to release the Power Cover, a keyboard accessory with a battery that lets the attached Surface go even longer between charges. The Power Cover should be backward-compatible with current Surface Pros, but because the Pro 2 should have better battery life to start with, it will get the most mileage from the accessory. Look also for a Surface docking station equipped with a variety of ports.
If you found the original Surface Pro interesting but not interesting enough, in other words, the Surface Pro 2 and its new accessories might do the trick. The battery life enhancements alone will be enough motivation for some.
But will the improvements be enough to convert the legions of genuine Surface skeptics? That's harder to say.
Windows 8.1 is a wild card. It will provide greater customization, a refined relationship between the desktop and the Modern UI, and revamped core apps. But the Modern UI has been too divisively received for Windows 8.1's appeal to be taken for granted.
The Surface Pro 2 is also likely to introduce a redesigned kickstand, but it's not clear how much benefit this will yield in practice, so for the moment, it's an unknown too. Aside from the aforementioned, the Surface Pro 2 is expected to be nearly identical to its predecessor.
