Hamilton to leave McLaren before end of the year?

They might be once Webber chips off to Ferrari

Are you comparing a drinking company, that show up from nowhere and can be gone in the same way, with a big constructor like Mercedes?

And if Mercedes drop's McLaren as engine supplier?

Apart Mercedes, Ferrari could be the only option, but with Alonso there it will never happen.

Red bull come out of No where but they won Constructors too and they can deliver best car time and time again so it can be a better opportunity along with Ferrari but as i said Redbull wasn't preferring Hamilton at this time and we don't know about Future

Officially they say that yes.

I think it's already a bit of a joke, because many young drivers have to pay to be there, only a very few don't.

Well I think Redbull Junior Driver program is Working fine
Yes they may have their Drivers under Performing but they will look for More Stronger Drivers in order to keep things going for Future

Well i don't think they will sign Lewis at any point but if Horner really think he fits then Lewis will enter into Redbull

In what way?

Don´t listen to the media or Horner while talking to the media.
He talks a bunch of crap but he knows he can´t deny Hamilton a seat, it would be too big of a deal, same with Ferrari.

As Domenicali said, "you would be foolish to turn down Hamilton a seat"

It´s the same as Vettel going to Ferrari, had he asked he would have been in.

But you said "bigger" joke.

Not sure what that means as Vettel himself came from that program.
Vergne, Ricciardo, Chandhok, Jamie, Buemi, Felipe all came from that.

Several F1 driver´s. some present some never really got their foot in solid.

But I don't think Hamilton would join Red bull Racing as he would be #2 Driver to vettel
And also Vettel didn't want to leave Redbull until Newey was there so they will have their #1 Driver and they will look for another only if Mark leaves Redbull

Alba.. DTM driver and Race of Champions, champion beating Vettel and Loeb in Semi and Finals.

Seems like they have a pretty solid idea of who to kick and who to keep judging by the kicks of Klien, Liuzzi, Speed.

I´d also like to see how you can say Vergne and Ricciardo has done worse.
The car is crap compared to last year, it is without a doubt the slowest car of the older teams.

Buemi is not even a world champion! He´s never been champion in anything.
Both him and Jamie were on vacation in STR for three years and failed to impress anyone.

Saying Vergne or Ricciardo is the same is funny, especially since Vergne for example has been in F1 for about 4 months or so... surely he should get atleast 12 before we judge him.
Or 36 if you want to compare him to Jamie or Buemi.

Perhaps a joke to you but if we look at what the goals was it´s clear they surpassed their own goals of nurturing driver´s into becoming world champions.

I also doubt you have to win in a STR to be selected for RBR, your performance is based on what you did over the whole year not just one day where the universe alligned for you.

You have to show consistently that you first of all is as quick as Vettel.
This is like rule 1 because they are only looking for the next Vettel,

I can´t disagree on that, he is a moron.

I think we may see Next Vettel by 2016 or 17 from Redbull Academy
And I Guess we are Discussing about Lewis not about RBR Junior Development Program

To me the Red Bull driver programme is like a TV competition.
2 lucky young drivers will get the chance to drive a Toro Rosso car for a couple of seasons before being unceremoniously dropped on their ass with no sponsors.

More than one engine manufacture out there.

P.U.R.E. is another option.
