Normally, when I see ～ことになる I translate it as "it is / has been decided that
～". However, in these few sentences the usage of ことになる is rather peculiar:

> 次期ＯＳ（ウインドウズ）の発売に合わせてパソコンを買い換えたいのですが、いつですか？ 来年後半らしいけど、延びる可能性もあるかもね。だから２年位待つ
> **ことになる** かな。

It's a snippet from BCCWJ, yahoo database. I am unsure if it's a dialogue or
monologue (speaker contemplating the possibility of Windows being delayed) or
what the exact function of ことになる is in the third sentence.

I translated the whole thing as:

> "I'd like to buy a new computer along with new release of OS (Windows), but
> when? It seems it'll be released by the half of the next year, but there's a
> possibility it'll be delayed. I'll wait for about 2 years."

How to translate ことになる in this sentence
There's nothing particularly peculiar about ～ことになる in your snippet. That
expression isn't limited to decisions, it simply expresses the logical result
or consequence of a given action or state of affairs.

In your snippet, the polite phrasing at the end of the question suggests a
dialogue, so I'd translate it as:

> I'd like to buy a new computer along with the next OS (Windows) release.
> When will that be? It's apparently coming out in the latter half of next
> year, but it could be delayed, so I guess you might **end up** wait **ing**
> about two years.

The ことになる simply expresses that a delay in the release will result in a wait
of about two years.
