"Milestone have confirmed they are listening to community feedback for the title,"
Lol. It seems they have selective hearing.
"...which has led to the "basis for the important upgrades that we have decided to play. The process of change will take some time, but we are pretty confident.."
These aren't upgrades. They are fixes for bugs that shouldn't have been in the initial release. Also, I see they have tuned the AI. That's also not an upgrade. That's attempting to fix something that is broken. My bet is it's a poor attempt. If a great developer tried to fix all this crap, it would take them a long time. But seeing this is milestone, I'm pretty confident they will not listen to their customers and they will fix only what they think they need to fix. It will take much longer then it should and will address only a small fraction of the bugs. Then they will copy the same bugs to ride 4.
PS. Death to Milestone! (Wow, I've really developed a loathing for them)
