That would be nice.

[sitifan]

Ivy: I'm wondering if you'd like to go to Lanyu again. Maybe we can go together.
Bruce: That would be nice.

In the above dialogue, can Bruce say "That will be nice"?

He can, although I feel that 'would' is more likely. At that moment, the trip is still hypothetical.

Bruce can say either; it depends upon what he wants.

If Bruce is not certain that we wants to go to Lanyu with Ivy, then he should say "that would be nice".

If Bruce wants to go Lanyu with Ivy, then he should respond with: Yes, that will be nice.
