ASUS is expected to launch the Zenfone 4 in July, and just like the previous Zenfone generations, it will come in multiple variants as shown in the leaked list.
According to a post in Zentalk, the list was from the Google Support website and shows five Zenfone 4 models:

Looking at the list, the base model would be the Zenfone 4 (ZE554KL) that comes in two different device names and model numbers depending on country availability. There’s the Zenfone 4 Max, which, as the name suggests, is the successor to the Zenfone 3 Max. ASUS is also bringing back its Selfie-centric smartphone with the Zenfone 4 Selfie. No Deluxe versions here but there’s a Zenfone Pro.
Hardware specs are still scarce, but we’ll definitely know more as we approach its launch date.

Prices are scarce kasi alam na nila what will happen if they release it this early. No one will be monitoring their products pag may price na. For sure overprice na naman mga yan.
