Snapdragon S4 Pro - perfect processor for Surface RT?

In my opinion, S4 Pro (A-15) is much better than Tegra 3 (A-8) - power efficiency, performance, architecture...

I know the Surface was announced many months ago, but... for me it isn't a wise decision for Microsoft to put a nice but a little bit outdated (and medicore regarding current standards) processor.

Same thing with Surface Pro. If it won't get the Haswell processor, it will be "outdated" from the start.

What do you think about Microsoft timing? I am still under the impression of the hardware as a whole, but little bit dissapointed when it comes to processor choice.
