The Yoga 11S was only recently introduced and is still a Lenovo.com and Best Buy exclusive. Personally, I would not expect to see a new model too soon. Given the XPS 12 is still the only convertible machine available with a 4th generation processor, my bet is the other manufactures are still working on designs or are waiting on optimized hardware, and are closer to a holiday season release than Labor Day. The fact that Lenovo's initial 4th gen machines in their other lines barely match battery life for 3rd gen, and they released the Helix with 3rd gen technology, makes me think the new processor versions are still on the drawing board. With respect to the current generation Yoga's keep in mind that while they use I series processors, performance is a bit lower than Surface Pro or Dell's XPS 12. For some reason that only makes sense to Lenovo, they used single channel RAM in the systems instead of dual channel. In addition the 11S i5 version uses a hamstrung version of the processor with lower turbo boost speeds. That is a difference I found very noticeable under heavy load tests. In spite of using a much lower resolution screen, the 11S also barely matches Surface Pro and falls short of bother the 3rd and 4th generation processor XPS 12s for battery life. Finally, although Lenovo improved the storage usage a bit, they still take too much of a 128GB drive for their system partitions. It is still a good mid range performer but those are the key limitations in my experience. BTW, you can get good deals on the Lenovo 13 from their outlet but regardless of outlet of Lenovo.com main online store, they have a really lousy return policy (15% restocking fee unless they made a mistake in the order).
