Whether Benson’s article is pure speculation or not, it doesn’t matter anymore. There’s too much noise around Honda at the moment for nothing to happen. There’s no smoke without a fire, all that sort of thing.
Personally, I think it’s not a matter of whether Honda will return or not, it’s a matter of when it will happen and if it will happen with McLaren, or an independent works team, or both…
Think about it. Honda already pretty much have the engine (not per-se but they could sort it out rather quickly compared to the level of development required by Mercedes or Ferrari, par example), there’s talks with McLaren, two free spots on the entry list for 2014, at least two teams that could go up for sale any given moment (Marussia and Force India) and a possible engine shortage (with Renault looking to limit the number of teams they supply and the Mercedes and Ferrari engines being quite expensive). These are all wide-open doors for Honda to enter the sport come 2014 or 2015.
I truly don’t think they are pondering whether they should come back to F1 or not. I think that decision has already been taken. I think they are trying to find the best option in terms of how and when they will make a comeback. Associating themselves with McLaren is just the most “popular” decision they could make, ergo the one that gets most of the attention from the fans and the media.
And I completely agree with @catracho504 here, Honda has the know how and the experience to place itself in contention very quickly. And yes, it’s gonna get nasty!
