Maybe, maybe not, we cannot say for sure. Even if they haven't, I think that there is nothing you can do that could really help your case. But this is only my personal opinion.

I am in a similar position: no response from any of the three reviewers. But I think that it does not have to be a bad news: maybe they do not need more details to take their decisions.

You have to remember that maybe they are not that interested by you research so they will just ask enough question to have a global view and not more.
