I see the W06 devouring the competition just like the W05, this year might actually be more successful for them as they will have focussed on their unreliability (their weak spot last year), it might be an all Mercedes year in terms of wins (unlikely though).
As a Lewis Hamilton fan I'm interested to see if he can address his Qualifying issues and with improved reliability and no double points this year he should secure his 3rd world title with a few races to go
Alonso in Mclarean Honda will be interesting to watch but I don't expect anything spectacular from them in the first year, perhaps next year. If they can be in the top 5 of the WCC that will be a huge step forward for them.
Shame about Force India's financial difficulties, I fear they could be close to collapse but I really hope they somehow make it through. It will be sad to see the 2016 Indian GP with no Indian team or drivers.
I don't know bro, Mercedes haven't shown their hand yet and by many accounts they have extended their advantage if not maintained the gap to the competition.
