As of this writing, there has not been an announcement made regarding an XP/TP event. That doesn't mean we won't have one some time in the not-too-distant future. After all, it's been rumored that the level cap may be raised to 85. ("Rumored", he said? What's he basing these "rumors" on?)
Chances are decent to excellent that a DRT sale will roll around some time before any major content addition and level cap increase, along with some sort of XP/TP event. (Copyright 2013, Kalvan)
