Describing speculative challenges for a new method in a paper When presenting a new method in a paper and you don't have any/sufficient empirical evidence of the limitations, what is the best way to introduce speculative challenges and potential mitigations?

I'm looking for the title of the section: is this part of the limitations section? my understanding was the limitations had to have empirical evidence.

What wording would be used for introducing them? 

Update: the field is interdisciplinary: a mixture of Business Administration and Computer Science.  The method is for Business Administration but relies on some Computer Science techniques and theory.
What about potential limitations?

I guess that you have at least some intuition or some loose arguments as to why you suspect that the things you are going to describe are indeed (possible) limitations. If not, you should not list them. If yes, add these to the section. Also you could discuss, what would be needed to overcome the limitations.
