Hard to say, patches and certs are still a bit byzantine on consoles. Some patches seem to come no problem, some stuff seems to be an ordeal.
It's under 800MB for sure--are you sure the game size is that high? Patches replace some of the data from the original file so a 400MB game with a 400MB update isn't necessarily going to end up as 800MB. I want to say it's something between 500 and 600MB on Vita 1.3 but I can check later
I know that's how it's supposed to work and since the Isaac patches were just small fixes the size shouldn't change at all. But look at this:
Download size in the store 345 MB
Patched with 1.01 801MB
Most up to date Steam build 311MB
They clearly fucked something up here.
