Well rumours turned out to be true and Samsung did launch 4 new Galaxy Pro models with top of the line hardware. Not only that, these tablets come with Android Kitkat 4.4 with a new touchwiz UI with a card boasting interface and better multitasking than before.
Things here in the leak that came from @evleaks today look more like a phone UX, probably to be featured on the next flagship and yes the new font is a refreshing change but it undeniably looks more flat and iOS like ever. Is this how the Galaxy S5 could appear? Could be, we are just months far from knowing the reality. There is no way to confirm the authenticity of these shots as of now.
