75% of Brawn GP has been sold to Mercedes & investors. Team to be renamed Mercedes GP. Mercedes to continue to supply engines to McLaren until 2015.

Yeah was always going to happen. Rumours are that Merc want Rosberg and Heidfeld so freezing out Button. Looks very likely JB will replace Heikki at McLaren - which will do me!!

Well They have signed one driver and talking to others and name their drivers in 2 weeks. They would like button.
It is more likely button will go to McLaren.

So many questions now with engines and development and the two teams etc.
What will happen in 2015........
Just lots and lots of questions with this news.

I think come 2015 McLaren will be making their own engines. The MP4-12C has their own engine (even the McLaren F1 had a BMW engine), so it looks as though they may be moving in that direction.
