Liverpool are currently in the process of redeveloping the Anfield Road End opposite the Kop, they have their new Main Stand down the side of the ground that towers over everything and the new Anfield Road stand has a similar profile - Liverpool's fans would like the Kop End redeveloped pretty quickly as it sort of feels wrong when it's the smallest stand in the ground.
The Holte will always be the place where the noise is, that's just how Villa Park is, but the movement of home fans into the lower North Stand and the cheap tickets there has changed the atmosphere at Villa Park in the last decade (for the better), and it'll be interesting to see what might happen if that end has a much bigger capacity. It's also been interesting to unexpectedly hear noise from the Upper Trinity this season as it's the only place people who don't come every week can get tickets. The Holte will always be the Holte, but there's definitely a flexibility to the Villa Park atmosphere.
I think we're a little less affected than Liverpool as the Holte is still a very large stand and the Kop, peculiarly, isn't actually that big a structure, which is kind of emphasised by the new developments. It'll be weird getting to Anfield and seeing that the famous Anfield Kop is the little stand at the end there.
A new North Stand would be a fabulous lasting reminder of the era of a pair of owners we have a lot to thank for.
