Take this with a grain of salt but it was within the last 2 or so months they said that we would not have more inventory space due to data size online. There was also an interview they asked what they meant by that and basically pointed blame at SONY not the consoles, saying it had to do with the online storage allotted them by Sony. The cloud storage limit basically from what I got out of it.
I figured it would be all over here so I didn't think to remember who said it, so it is what it is.
Edit: but yeah they also said it would pose longer loading etc as above
