Hello.

What is the difference in meaning if we use would arrive / would be arriving like future in the past?


- Our computer was broken and we hoped the new one would arrive / would be arriving soon.

Thanks.

Both sound correct, and I can't think of any real difference in meaning. Maybe the progressive aspect seems a little less formal; I might expect more to hear that version spoken, and the simple tense might be more common in formal writing. But I really think the 2 versions mean the same thing in this case.
