I don't know where the "hopefully one year of Early Access" statement is from, I do see it quoted on these forums, but on the Steam store page it actually says they "expect" around one year, and that makes a big difference:
You typically use "expect" only when you know there is a good chance of something happening. No one would say "I expect to win the lottery." Because they know that is not likely to happen. You can only say, "I hope to win."
Likewise, when TW says they expect EA to last around one year, TW is saying that they believe there is a good chance that EA will conclude in around one year. It is not just a statement of desire or hopefulness, it is a statement about what TW thinks is likely to happen. And that wording will create expectations that, when unfulfilled, can lead to disappointment.
At this point, I don't know whether TW honestly believes that they can still pull off the EA in around 7-8 months from now. If they still believe they can do it, then keep that same wording. Otherwise, if they have honest doubts about the timeline, I think it would be wise for TW to modify this language since some people are claiming that they have been mislead by the description of the game.
I also think they may want to remove the "1 year" timeline from the store page. Why? Because of the saying "under promise, over deliver." In case someone is not familiar with the saying, it means that you should make modest promises, but over perform so that you exceed expectations. This way, not only do you give yourself leeway in case something goes wrong, but if you finish your project ahead of time, you have customers who are impressed.
On the other hand, if you "over promise, under deliver" you create unrealistic expectations that can lead to disappointment.

Approximately how long will this game be in Early Access?
It makes a big difference because "expect" carries a stronger meaning than "hope." "Expect" typically means you think something is likely going to happen, whereas "hope" only means a desire for something to happen, it says nothing about how likely something is going to happen.“While we do not have a set date for a full release at this moment in time, we expect that the game will be in early access for around a year.

Expect:
regard (something) as likely to happen.
Hope:
want something to happen or be the case.
TLDR: TW never said they hope that EA will end in around one year, they said they expect EA to end in around one year. At least on the Steam store page. It may benefit them to change it.
