The way things seem lookin that more and more groups which will hit that 4-5 year bar of activity will start to release one album in 2 years, maybe even in 3 and it will be that roll-out which we already seen happening with pre-release MV and then after month, or month and a half another MV the main title will drop.
It seems inevitable that this will happen more often after sales going up so crazy. We might be soon stuck in situation that more often dropped releases (at least 2 in a year) by groups from mid-size agencies will become that one thing which will keep us interested and still will make us "invest" our time into getting to know some new groups or following some additional content like youtube variety shows etc.
Don't attack me with money this, money that. After all most of us came to kpop for music and great MV's, so it's obvious we don't want to see it like once in two years, like let's not make our fav being in same level as auntie's Betty birthday which we attend each 2-3 years xD
