(a)round the corner
1. In close proximity to another location. Said especially when traveling by car, often when literally approaching a corner. The store isn't far from here, it's just around the corner.
2. Imminent or likely to happen very soon. My little brother believes that an alien invasion is right around the corner and that we should prepare ourselves for life on another planet. Our company is devoted to the self-driving car and believes that its widespread use is right around the corner.
