Given the delay between the other thread being made and this news post, I wonder if the mods know something that effectively confirms this inclusion. I guess us plebs will know in a few days once the World Tour streams starts.
I don't mind if it's just static rain. Dynamic weather is too much for the PS4 to handle with GTS level of graphics and I'd rather they maintain smooth gameplay at all times. I hope this time they also take the time to model wet lines and puddles/aquaplaning though. Previously in GT5/6 wet lines are not that apparent and rain driving just feels like a general grip de-multiplier. The Northern Isle missions also still feels like this. And even that doesn't use wet tyres. After driving rain in ACC PD have a lot on their plate to catch up.
