I am curious about this as well. It was one of the key reasons I waited for the Haswell version, to be able to turn the Surface on/off in the same way that people use iPads. Pretty gutted it's not been included.
According speculation on the Reddit AMAA it is due to the Surface not being fanless: "a limit from microsoft, One of the 3(IIRC) conditions of connected standby was a fanless / passive cooling design".

The fanless/passive cooling requirement only applies to the device while it's in connected standby mode. It is not a strict requirement that the device not use active cooling while it's active. Therefore, Surface Pro 2 is not disqualified because it has a fan. It might be possible through firmware, OS, and drivers to scale down the CPU clock speed enough when in connected standby mode to make passive cooling feasible. For Example, one CPU core clocked down to 300MHz might allow for passive cooling. It all comes down to the minimum heat the Surface Pro 2's Haswell CPU generates if the performance is scaled down to it's lowest possible settings.
I think they won't add it in Pro 2. Because this is more ultrabook than tablet.
Personally I really disappointed with second Surface generation. RT version useless, Pro version more like notebook.
Where is hell good Tablet solution?
I have ASUS VivoTab Smart and I like it because it has Atom inside, full Windows version and Connected standby! I only hate bad display (compared to iPad retina one).
Why MS choose to ignore Atom and again release RT version!?
