town portals were being completely removed from Diablo III. Now, this was something that was being tossed about for some time since Diablo III's development. As it has been mentioned, there was one main reason that the development was looking for a way to remove them. They had decided that town portals just made it too easy for the game's action to be avoided. At any time in Diablo II, minus the
Rite of Passage quest, a player could simply click on a scroll and instantly remove themselves from any present danger. They could restock their potions and continue their attempt to defeat whatever foe was giving them problems. Because of this mechanic, many monsters had to be scaled up to compensate for this retreat by being able to kill players within one to a few hits. Overall, this one simple mechanic caused many more issues through other various systems. 
Health Globes were also added, removing the necessity to constantly go to town to restock on potions. With these three mechanics in place, it appeared as though most of the town portal's uses were covered without any of the disadvantages they caused. However, it appears through Blizzard's constant iteration process, it seems like this still is not enough for the loot heavy, quick-pace game that is Diablo.

Also I never said you can just use them anywhere anytime as much as you want.
On a related note, it was also mentioned, by a user, about the ability to quickly join others without town portals. In Diablo II, any person joining a game could instantly join their friends in the fight by one of the players opening a portal for them. Without this system, even the closely placed waypoints still seemed to be too much of a hassle for players to go through. In Diablo III, players will still be able to group up instantly when wanting to join the fight.

With all of these changes still going, it is clear to see that the Diablo III team is still hard at work perfecting the game. However, do not let this trick you into thinking that our coveted Diablo III will never be released or that it is doomed to continuous push-backs. Blizzard always continues progress on their games up until release and then after.
