Here's my proof. ON DBO TW facebook page, I posted on their wall asking if they're going to raise the level cap, they said: We are going to release new patch very soon and you can reach higher level then. Also I posted this on their official facebook page for non-believers.
I also crossed out a few things for personal reasons.
we know from the start and from korean version that the normal gap is 55 so maybe its the same here? also there is no reason to have 55 lvl from the 1st day we see the same with korean beta's
