mousesports team at The International 2012, l-r: Black^, Bamboe, 1437, KuroKy, SingSing
The mousesports organisation is yet to comment on the situation, but with the team in need of flights to Kiev - collectively valued at approximately 2,000€ - James '2GD' Harding (host of The GD Show) stepped in to help them, and agreed for his company to make a one-off investment in the team to finance their trip.
2GD has stated that the team will be parting ways with mousesports and play under an as-of-yet undecided temporary name during the duration of the competition in Kiev, and are likely to reform after its conclusion.
UPDATE: mousesports have posted a statement on their Facebook page, in which they clarify the circumstances of their team's release:
Due to a recent article posted on joinDOTA.com we wanted to clarify the situation about the current mousesports Dota 2 team. After The International, our team partially disbanded and we've set up a temporary Dota 2 lineup for the time beeing. Before the Starladder Finals, we've agreed with the players to release them out of their running contracts in October 2012, since some wanted to pursue a different career approach in Dota 2. It wouldn't make any sense to send a team to Kiev, that isn't contracted and won't play for mousesports anymore, so mousesports won't finance the team's trip to Kiev. The unpaid trip to Kiev is in no relation with the mousesports sponsors, as it was a decision by mousesports to not pay the travel and accomodation costs for a disbanded team. Despite all this confusion, we're wishing our former temporary Dota 2 team best of luck in Kiev.
