I'm in the it's gone for good category.
I'd love to be wrong and have no particular insight other than gut
I was never in the group that thought AP's were gone for good, I was 10000% sure they'd return. No way was Disney going to be the only theme park (practically) that had no pass
I was certain room discounts would return, though they never left honestly. Other than Christmas week, I've never in over 10 years of 5, 6 trips a year, not gotten a room discount.
Dining Plan, 100% sure it would return because Disney makes a lot of money on it. They've tricked guests in to thinking it's a bargain and it is NOT. Disney makes money on it, that's why it's back. Not because it is a loss point.
TiW I'm afraid was a loss point. That discount on TS along with alcohol was big. We always saved more than the card cost. I'm guessing majority of other card holders did too. Disney lost money on TiW as a whole, I'm betting. That is why it is very unlikely to return.
If it does, it would be at such an increase it is unlikely to be worth it.
Disney is only offering things that benefit Disney
