Is this the millionth time you've asked about the (7)? When the developers have updates, they'll post them. Otherwise, there are no updates. Many developers work. Some have school and work. Others have a family to take care of. I wake up each morning at 6AM, leave my door at 7 and sometimes don't get home sometimes until as late as 10 or even 11 PM, with even more work waiting for me at home. Some developers have it worse and work non stop and simply don't have time for routes. Some routes can go months with literally zero progress made because the developers simply have no time. The 7 will be released within a matter of time and constantly asking about it won't make it come out any sooner.
As for the R142, that is in development to. If you want an R142 with animated wheels, you can go learn, experiment, play around and add them yourself for the time being like me
