It is not clear when the announcement will be made.
There have been some rumours in recent days that the team may have the backing of none other than Bernie Ecclestone. This would not be a surprise as Ecclestone is keen to make sure that the teams are not unanimous within the Formula One Teams' Association (FOTA) and having a financial interest in one of them is a good way to ensure that this happens.
It is believed that the majority of the money to run the team will be coming from Honda itself as it is cheaper to pay to keep the team alive than it is to lay off all the staff.
