2019 to 2025 is crazy for a track. Let's be generous and say 2021, or even 2022. I would imagine this trip also coincided with the track scanning (though I could be wrong).
From the little I've seen on YouTube, the visuals do look good, so I'm not complaining in a sense, I don't want the quality to drop. I know it's a lot of work, but even if they could buffer up with enough so they could release one track every six months while still taking the time they want to get it up to their standards.
It might also be that this track has been done for a while and they've had it on the backburner to release in the future. But if that's the case, why not have other tracks ready to go?
Even if it was 6, or 8 months per track, I think people would be happier than it is now. I'm happy we got two tracks, don't get me wrong, but the output as GT7 has gone on, is low. Can they really not afford a buffer, even with their quality level?
