Yes, Grenå 4 won't get to it's final decision until 2023 - if the process runs smoothly!
No renders at all of the current version have been released, that's why the link you posted to the City's page about the project is using its default picture up top.
I'm looking forward to it getting built, but at first I'm just waiting for renders to be released
Playce is indeed a huge deal. For its height, but I'd also say for its location. Spreads out the skyline by quite a bit, as does Myvatten. Grenå 4 and Geysir otoh will be the first towers to make the skyline denser.
