Never underestimate Capcom when it has to do with Swtch support. 500yen increase over PS4 for RE4. Better don't guess where price will go if they ever try with RE5 and 6.

I checked Japanese PS Store for file sizes:
Resident Evil 5 - 16,93GB
Resident Evil 6 - 17,20GB
It doesn't look likely these will get physical releases either unless Capcom sees them as first time at Nintendo systems and go even higher at price.
Neither this can happen with the size of all these games added together:
[PS4] Resident Evil Value Pack {Resident Evil 0 HD Remaster \ Resident Evil HD Remaster \ Resident Evil 4 \ Resident Evil 5 \ Resident Evil 6} <ADV> (Capcom) {2018.12.13} (¥8.100)
With the rate Capcom operates on Switch it could be well into 2020 until all these are ported and prices of carts will go lower until then.
*All these assuming Capcom intents to make the move for RE5 and 6, nothing is given for Switch from Capcom.
