I don't know when GT 7 will be on store shelves but personally i prefer a bit late on 2021 ( second half).
What happened in the past i think doesn't play any significant role since there was no pandemic and financial crisis together as we have globally right now and from how things are going looks like both of them are gonna keep us " company" for a quite long time.
In my country there is None ps5 for sale and nobody knows when ,if and how much pieces there will be available .
I guess the same happens and in other countries and as i wrote in the past , there's no way to release such an anticipating title like GT 7 without cover a serious amount of ps5 worldwide.
Since I'll buy ps5 only for Gt 7 ,the later the better for me ,but i really understand the fans that waiting for it ,on the other hand ,day by day , worldwide, the consequences that Covid 19 leave behind are growing so much that it will start to became a " joke" to worry or worst to add another problem in someone's life for when a game title will released .
Peoples loosing their jobs every day due to quarantine conditions , the summer pass with the tourism at his lowest ever and ( you can figure the billions lost worldwide) and we can't see a light in the hole we are fall in.
My point ?
Be happy you're safe and have your health and job and your lovely persons around you and leave the rest to worry others ,Sony ,Pd etc.
