I just had a look at the tv shcedule for the highlights of the Russian race next weekend. The race starts at 12.10pm our time I believe and they're not showing the highlights until 6.45pm. So I don't think the three hour gap will make that much difference in all honesty. If they can't start it until 6.55pm, it's only 10 minutes later than this year as they don't seem to choose to start it much before then anyway even when they can.
Yes they already show the later starting highlights races late in the day, I just record them and watch them next day or I'd fall sleep through them anyway.
