Usage of 「V+見込みです」


I want to understand the usage for ’V＋見込みです’。I want to say something is
expected to get delayed, so which is better 「～が遅れる見込みです」or 「～が遅れてしまう見込みです」.I
have added しまうfor an expression of disappointment, is it incorrect in this
context?




> 「Verb in て-Form + **しまう** + 見込{みこ}みです」

While I would not consider this expression incorrect per se, I know for
certain that it would be far less common than:

> 「Verb in Dictionary Form + 見込{みこ}みです」 used in conjunction with a phrase
> expressing disappointment.

You could say, for instance:

「残念{ざんねん}ですが、電車{でんしゃ}が遅{おく}れる見込みです。」 or

「電車が遅れる見込みだと聞{き}いて残念です。」

If you **_must_** , however, use 「しまう」 for some reason and still want to sound
perfectly natural, you could use it by changing 「見込みです」 to 「可能性{かのうせい}があります」.
I know this might not be what you wanted to know, but for future reference, I
added it.

> 「電車が遅れて **しまう** 可能性があります。」
