I was initially excited at the prospect of SimCity 5 being released, but after reading into the design and the plan, I can safely say it's going to be a load of crap. It requires an always-on Internet connection, they say it's for a community based experience, and a little bit for DRM. And when they decide to turn off the servers, that's it for SimCity 5.
I also believe there will be no player-customizable content, certainly at least not to the extent that SimCity 4 still has. And that is why I won't purchase it, and it frustrates me because I know full well others will buy it expecting an improvement over SC4, and it won't, it'll be such a piece of crap. And if it sells poorly, EA will decide there's no future in the SimCity games and kill off any further expansions, and if it sells well, they'll kill it with more microtransactions. I hope someone starts a proper City simulator through KickStarter or similar, I'll throw money at that.
