〜そうです(様態)~sou desu
looks about to happen
Attach 「〜そうです」 to a verb stem to predict an imminent change from visible signs, without certainty.
How it works

Look at the shaking shelf. The product is still on it—what do you think will happen next?

Use “verb + そうです” when visible signs suggest that a change is about to happen.

Remove 「ます」 from the verb’s ます form, then add 「そうです」. Do not attach it to the dictionary form.

This expresses a judgment based on signs, not your own plan. It does not guarantee that the event will happen.

In the example, 「もう」 emphasizes that the product is nearly sold out. 「売り切れそう」 still predicts this before it has sold out.
