这 / 那 + 要看 / 得看 + [noun]
这 / 那 + 要看 / 得看 + [question clause]
[topic] + 要看 / 得看 + [question clause]
要看 and 得看 mean "it depends on". The thing it depends on comes straight after 看, and the sentence usually starts with 这 or 那, pointing back at what was just asked.
The two are close. 得看 sounds a little firmer: you can't answer until you know.
What follows 看 is often a question: an A-not-A form, or a clause with 什么, 怎么样, 多少 or 谁. It stays in question form, but the sentence as a whole is a statement and ends in 。.
The topic can come first, as here, instead of 这 or 那.
看情况 is the short answer: "it depends", "we'll see". It can stand alone or follow 要 / 得.
依靠 means relying on a person or on support. It does not mean "it depends on" a condition.
