Let me give you an example. The government has just introduced new legislation aimed to tackle the high unemployment rate. A colleague of mine is asking my opinion on it. So I reply with: "Well, it's hard to tell. Too many factors are involved. Let's see how it will play out".
Now, suppose there's been a few weeks since the same legislation came into effect. Wouldn't it be more natural in this case to answer the same question as follows: "Well, It's only been a few weeks. It's too early to judge. Let's see how it plays out"?
