The first reference can be seen on the laptop where Coco Bandicoot appears to look at a scene from Uncharted 4. This has been changed to a shot of Crash Bandicoot. The other reference was in the form of a sticker on the laptop for Coco Bandicoot while the last reference was seen as a picture of Nathan Drake was featured in the house of Crash Bandicoot. It is not hard to see it getting removed as well.
There will be a more thorough post once more details emerge in the future.
