New Marksmen Items and Crit Melees

So, I'm sure we've all seen the bit on Surrender at 20 or somewhere where marksmen items are being talked about with some items being changed like Essence Reaver and everything...

I was wondering how many of these items are going to be usable on Tryn, Yi, and Yasuo? They've all had to use the Marksmen items and with Marksmen being changed as well as their items, what... What can we expect to affect these specific three?
