Well, the easiest research for Sony would be searching in the trophy-list of each PSN-account with a registered PS4. How many of these PS4-accounts (a subset of all PSN-accounts) have no PS3-Uncharted-1/2/3-achievements?

That's not the interesting part for the publisher though. They only care about actual (first) sales. The 50% new owners is much more interesting to them. Anyone who has or had a ps3 had plenty of time to try out the series, why would they buy a new copy now if they didn't think the series was worth it the first or second or third time. Yet take the attach ratio for the series on ps3 and apply that to the new ps4 owners and you have a sales forecast.
It's kinda silly to boast how many people didn't like your game :) Though turn it around and they're saying 40% of people that migrated form ps3 to ps4 have played Uncharted, which is indeed easy to check by looking at trophies. That's a rather impressive ratio and since they can also see how many people double dipped on The last of us, that could add up.
