"Will" and "would" for predictions:
We can use "will" for a prediction:

- They're going to Delhi for the weekend.--That will be nice.
We use "would" for a past prediction or a prediction about a
possible situation.
PAST:
- At midnight James was still working. He would be tired the next day.
POSSIBLE:
- How about going to Netherlands next weekend?--That would be nice. I wouldn't enjoy a camping holiday.
We can use "shall" instead of "will", and
"should" instead of "would", but only in the first person,
after " I " and
"We".
- I will/shall go to the party.
- We would/should like to come with you all.

Shall and Should are a little formal here.
