The Sims 4

In April 2010, an EA employee leaked information on Twitter that development of The Sims 4 had begun. However, that is the only information available.

In April 1st 2012, which is April Fools' Day, SimsVIP pranked viewers by photoshopping images which enthralled users making them believe The Sims 4 was being started on by creating a post with the title The Sims 4 Press Release + Origin Listing *Leak*.

This is what the post shows:

EA REVEALS FIRST DETAILS OF NEXT-GENERATION FLAGSHIP PC GAME - The Sims 4 Gives You Complete Freedom, Inspiring You With Endless Creative Possibilities. A teaser trailer was released on YouTube and was confirmed by EA as The Sims 4. The post included information on what's involved in The Sims 4 such as; "Sims can go beyond the boundaries of their neighborhood, and immerse themselves in an open subhood, interacting with other Sims using our new deeper personality system" “It is this type of open-ended gameplay that inspires endless creative possibilities. In addition the new goals and rewards systems will give players of all kinds from core gamers to storytellers the ability to enjoy long-term gameplay.” New Weather System — Every Day is an Unpredictable Day “The Weather System really delivers what the players have been asking for – a unique gaming experience offering new seasonal, outdoor activities that players can engage in. And because each season unfolds differently, winter, spring, summer and fall will look different than the year before, guaranteeing a fresh experience each season.”

On June 2012, a user named Kabuto from two different fan sites, SimsVIP and Simprograms, predicted when The Sims 4 will be released. This is what he commented on:

It mean no pack in 2013 because it’s the end of The Sims 3. If we follow the Sims lifecycle (4.5 years) 02/2000 : The Sims 09/2004 : The Sims 2 06/2009 : The Sims 3 The Sims 4 should be released after 09/2013 So I understand SP8 and EP8 must be the last packs, they must released them before 2013

If the rumored Seaside Stuff pack and Seasons expansion pack are announced officially, there should be 2 more EPs and 2 more SPs (some rumors state that The Sims 3 will have 10 EPs and 10 SPs) for EA to release.
