I loved Elder Scrolls 3 and 4, and FO3. Great games. A game company can only develop so many games in a year. TES4 was a HUGE success... and many years later, we don't have 5. Why? Because this company is busy with other projects that won't sell nearly as well. If I was a stockholder, I'd be selling. It makes no sense to spend company resources on less popular franchises IF it also means you won't continue your most popular one.
Do you know how long it takes to make and do basic testing on a large-scale RPG? Let's look at Beth's release dates just for the Elder Scrolls series.
Arena (Elder Scrolls 1) - 1994
Daggerfall (Elder Scrolls 2) - 1996
Morrowind (Elder Scrolls 3) - 2002
Oblivion (Elder Scrolls 4) - 2006
There's also supposedly an Elder Scrolls MMO, and Elder Scrolls 5 in the works.
You're acting like they're long overdue for the next release, but guess what? They aren't. Calm down, stop shrieking, let them do their thing, and do your research before you enter into histrionics.
