5.50 FW Released now

So less than one hour 5.50 was released.
Does this means 5.05 jailbreak+kernel acces will be release soon?

Question: I bought TLOU 3 days ago in my ps4 slim, then I bought yesterday a ps4 pro. I was going to install and log in my ps4 slim account with the pro (since I deleted the games on slim)
Would be possible to log-in and download the game from PS Store without updating?
