Yes, they were expecting to be taken over last week which is why they confirmed they would be in Turkey, but the deal fell through so they are not able to fund it anymore, and Honda have already given them heap's of cash as well as free engines, gearboxes etc to keep them going.
With Honda having their own F1 team, it is pretty much stupid for them to keep looking after a competitors interests, especially if the situation gets no better.
It's not just the small teams who are questioning their future in the sport, but also Renault do no think it is a financially viable sport, although they have committed until the 2011 season iirc.
There isnt much future in the sport imho, and it's about to get even harder for the small teams, as the big boys will no longer be able to support them by selling them customized engines etc in 2010.
F1 is quite simply killing itself. There will need to be BIG changes to the sport, if it is to remain the dominant force in FIA Motor Racing in 10 years time.
