@ChugKendall yeah an additional cost to upgrade - If someone knows for a fact they'll upgrade when given the chance, I recommend just splurging now on Gold or Ultimate because you'll get all the other extras. My guess is the next-gen upgrade will cost about $20-30 by itself
For comparison, Ghost of Tsushima will cost roughly $30CDN (probably around $20USD) for its next-gen upgrade and I'm fairly certain both the Nioh Collection and Death Stranding are quite similar in price structure too so I guess it isn't too far out of the ordinary. Something like Jedi Fallen Order and Control have free upgrades because there isn't a huge difference between versions - 2042 will have far greater stability in addition to more map usage and higher player counts.
