The sponsor we've all got associated with the rise of Europe from 2010 is now back with a new team. At least four-fifths of their roster is new.

What basically was Hard Team is now DTS with some modifications. McDeath, Funn1k and dubas team up with Plet and ArtStyle, who was in the previous DTS team before he left to join up with Na`Vi. Not too soon afterwards, DTS dropped DotA and the players continued under the name of Garaj, who were then picked up by Moscow5.

But now the name DTS is back, and it has a fearsome legacy around it indeed. Hard Team, featuring McDeath and Funn1, have recently been using rather aggressive non-carry based strategies, something we've come to attribute to the ArtStyle way of playing DotA.
XPEH, owner of DTS, gives the following reason for the comeback:
"Basically, the energy is found again to reclaim the top position of Europe."
It's a summarized version, the original statement can be found following the link at the bottom.

Roster of DTS
Alexand 'McDeath' Konstantinov
Gleb 'Funn1k' Lipatnikov
Vitaliy 'dubas' Luhtan
Andrew 'Plet' Pereprosov
Ivan 'Artstyle' Antonov

We won't have to wait long for DTS to produce positive (or negative) results, as they'll be playing the Intel Challenge SuperCup offline playoffs this weekend.
