Let’s pencil it in. — We set a date, but it can still be erased.
Down the road. In the pipeline. — In the future, not yet fixed.
TBD. — To be determined.
Next quarter. Q3. The back half of the year. — The units of the planning calendar.
The out years. — The later years of a multiyear budget, where the numbers are least firm.
Eventually. Someday. — No date, and therefore no commitment.
