Expand/create new regions

I think I speak for many of us; that after many years of playing the game, amassing a huge amount of buildings and specialisations that are piling up in storage with nowhere to put them, as well as land deeds that can't be used because there is no more land (I have almost 40 land deeds at present)........isn't it time to go beyond the occasional strip of extra squares given to us in our main cities and either expand our regions giving us more land to use, or even create more regions? It's going to get to a point where many long-term players will hit a wall and have no further incentive to play on. Give us more land!
