Yes, there was a rumor mainly on twitter that LeMans will withdraw from GT500 few days ago.
It was a rumor that Toyota won't deliver GT500 machine to LeMans.
Team LeMans' parent company is Okayama International Circuit, and its parent company is an auto parts manufacturer ASKA.
Therefore, it's not because of the lack of funds of the team.
And Akio Toyoda commented that this year's 6 teams would compete by new Supra.
So I think LeMans will participate in GT500 also next season.
