Alright, why not being more accurate then.
There's either 2 situations:
1. Armagan has completed the game, and is releasing updates one at a time for his own personal amusement. In this case, we can get accurate dates.
2. Armagan releases updates when he feels the update is advanced enough, stable enough and unlikely to break the game. In this case, it's impossible to get an accurate date before the fact.
Look at it this way - the longer the update takes, the more stuff it's likely to change or add. A shorter development time means less stuff added.
