The exclusivity deals appear to have been good for no one involved: Epic, Square Enix, Sony, or customers, so I think we've seen the last of them outside of things Epic publishes themselves.
How was it bad for epic? They would've made more from cuts on sales on steam than selling the full game at the lower rates on their own store? God I wonder how dismal their customer engagement rate is.
According to a friend who had the displeasure of looking at the file size, he claims it's 170GB when all is said and done... Stupid Sony square refusing to let steam preload...
170 GB is insane. Publishers should really get punished for making larger than average deliveries. Most of that size usage usually comes from poor optimization.
They're typically optimizing for fidelity and performance ahead of install size. Multiple LODs can balloon an install size quite quickly, but they'll give you better bang for your buck in other areas, and storage space is a concern that dissipates more in time, as you upgrade to newer machines.
