Because PS3 and PS4 are different consoles. If you have Minecraft PS3 and try inserting it to a PS4, it won't be able to load because it changes the features in the disc. You might need to sell your Minecraft for PS3 and use the money to buy it for PS4.
Yes you can BUT it only gos to 1.13 which is the sea update if you want the nether update or the new 1.17 cave update buy ps4, switch, phone, or anything bedrock check what version of minecraft your on on the minecraft.net!! :-)
Yes, you'll be able to download the updates through the PlayStation Store.
At the ps4 "dashboard" you will scroll to the game minecraft then press the OPTIONS button or PAUSE button and then it should give an option that reads : Check for Update then click that and update it and then it should say your downloads in the NOTIFICATIONS bar. P.S I think you need a membership for playstation to access online features but I hope I was a little help at least.
When is Minecraft coming out on disc
If Minecraft hasn't updated for you, you may have to force an update. When Minecraft opens, check the force update option and then log in. That should make Minecraft update for you.
You cannot have babies in Minecraft for PS4. Animals can have babies, but your character cannot.
