User blog:DLGsW/How many escape pods / life pods are out there?

I was just wondetring how many life pods are out there. So far I've encountered about three (include the one you landed with) 13, 17 and 5. Is there any more than that? If so then can we assume that there are (or going to be) 17 lifepods in total, if not more? I just wounder how many have been discovered so far.
