I agree, the 4X is a huge step from the 2X, everything i didn't like about the 2X has been improved in the 4X like the size and weight of the phone, the o2x is too big and heavy for a 4", now the 4X is perfect for the 4,7" screen, louder speaker, the only thing i think is a step down from the 2X is the MHL-HDMI, i'd rather have HDMI port like the 2X has.
For the reasons above i will buy a 4X later this year, because LG has changed for the better IMO.
