I think X3 still has a big part of this timeline. It might be altered, but def not omitted or changed drastically.
I haven't seen any connections with origins tbh. Nonetheless, I don't think the origin movie really matters. Every writer has their own orogin story. All we need to know is Stryker manipulated Logan, Logan got metal on his claws, and that he hates Sabertooth.
Kayla was blatantly referenced in The Wolverine, so there's one connection.
Logan's entire WWII arc and bone claws arc are all aspects that were introduced and implemented in X-Men Origins: Wolverine, and they were included in The Wolverine expecting the audience to have pre-existing knowledge of these elements. Elements that, in the film universe, can only have come from X-Men Origins: Wolverine.
That movie is very much a part of the timeline.
