The answer will depend on ... The answer depends on ... These are both correct ways to start a sentence. The phrase you are asking about can only be used within a sentence in very specific circumstances. For example: My new house will be very big, but exactly how big it will be depends on how much money I have. So your original feeling was correct! Congratulations.

HI Elena For the avoidance of doubt - NO - this expression does not exist in English. We say "It depends on," OR "It will depend on." There should not be a "be," in the expression.

You've taken the phrase out of context. The examples I've found include: Which it will be depends on... What it will be depends on... ...how bad it will be depends on... In all cases the "it will be" part is included in the subject clause, eg. "[Which it will be] depends on..." No mystery here.

hi, to answer your question, you have to realize that "depend" is a regular verb, and when you write it like "it depends on...", wich is correct, is because is writen in present tense. And when you write "it will depend on..." you are expresing it in a future tense wich is also correct, because the "will" verb is supporting "depend" to express future. I hope taht clears it up.

Interestingly, even the COCA corpus shows some matches. And first I saw it in the New English File textbook, published by Oxford UP...
