We will remember Yorick Mori.
Anyways, Yorick has a few items to look forward to with the item changes.
Manamune is pretty much the same, if slightly more expensive.
Death's Dance will likely let you heal based on the damage dealt by your Ghoul's basic attacks and it will make you take a certain amount of damage as a bleed over time, which you may be able to sustain though.
Black Cleaver is still great for rapidly shredding an enemies armor due to your Ghoul's basic attacks.
Sterak's Gage is still good for the shield and durability.
Iceborn Gauntlet now provides more CDR and armor, has a larger slow field, and no longer provides AP (which only affects your W).
Spirit Visage's stats have been increased by 100HP and 10MR.
While you can't pick all of them without overcapping on CDR, I feel that his itemization options have improved.
I can see him being built more offensively in the future due to new possibilities in itemization.
(Ninja Tabi or Mercury Treads) + Manamune + Death's Dance + Sterak's Gage + Spirit Visage + (Iceborn Gauntlet or Frozen Heart) will be pretty tough to deal with later in the game and offer a lot of damage and durability, especially combined with his passive. Obviously the items built and their order will change massively from game to game, but I don't think it will be as bad as you may think.
Mana is going to be an issue early-game, but that can be worked around in many cases.
Also, I believe that starting gold is going to be 500 now. If you wanted to, you could easily start with a Sapphire Crystal + 3 Health Potions (waiting for 5 gold) and get an early Tear of the Goddess.
