So here are the upcoming plans for beta update 3.0 as well as plans for the full release.

Beta 3.0/St. Patrick's day event:

Beta 3.0 is planned to be released on the 13th (no specific time) but the content for the St. Patrick's day event will only be accessible through the 14-20. During this time you will be able to purchase a special St. Patrick's hat and there will be an additional zombie. This zombie will be a spin off of the bloated zombie (the one in red) except this one will be wearing green and will not hurt players when it blows up. Instead, when this zombie is killed he will explode coins. This will be a great way for new players to get some extra money, just make sure you aren't killing a bloated zombie instead. This update will also include the addition of molitovs. In order to make a molitov, you will first have to find some liquor and then you will have to right click the item in your inventory to add the cloth (this will require one bandage per bottle). You may then equip the molitov but you will only be able to use it if you have matches (one match per molitov).

This update will also introduce the tutorial and the start of the safe house progression (main missions).

Full Release:

The only plans so far is that the full release will be the next big patch after beta 3.0. It will run as beta 4.0 until any major bugs are fixed and then patched as the full release.
