A bit surprised seeing all this stuff about possible news from Brazil and Senna. It's really easy to jump up in the air and say we might get Senna's cars (namely the MP4/4), Senna himself in some form (helmet, suit, etc) or Interlagos in the game, but I'm going to take a step back and have zero expectations.
However, I will say that since GT3 I have wished for real classic F1 cars, especially those from Senna -- particularly the MP4/4 and MP4/5, the latter my personal favourite, with such a beautiful design and the V10 Honda (and for its engraving in history with that Senna/Prost incident at Suzuka), but also the MP4/5B, 6, 7 and 8.
And while I already said I'm keeping my expectations to a bare minimum/nothing, we did see Senna's Lotus 99T on the Goodwood monument in the game. I've been hoping since that reveal that all those cars are driveable and we'll just have to see. Obviously I'd take any of Senna's McLaren's over that Lotus (or even the JPS livery 97T or 98T), but if any F1 car(s) from the the early 1990s or earlier make it into the game I'll be extremely happy.
From a neutral perspective, you'd have to think the MP4/4 has the biggest chance of any of them making it -- not only Honda's biggest achievement in Formula One but McLaren's and also the most successful car in F1 history, and furthermore a car that won the world championship in Japan by the country's (by far) most adored non-Japanese driver ever.
But again, we get nowhere with huge expectations and all this talk is probably massively unfair because it's pure speculation.
Fans always forget Prost, don't know why. He is a true legend, had the strongest line up of teammates the history of motorsports has ever seen (Rosberg, Piquet, Senna, Mansell, Hill - they share 9 WDC between them) and by todays point system he would be a 7 times WDC like Michael.
Piquet was never Prost's teammate, but you forgot Lauda. All those others are true though and Prost probably did have the most spectacular roster of teammates through his career. He was only beaten by Lauda by a half point and Senna by three points, but also beat them both following the years he lost to them.
Senna had an ego problem that made him accept nothing but the best. Taking someone else out of a race for personal gain is reckless and pretty damn low.
Suzuka 1990 is so often massively taken out of context. It's not a simple "if I take him out, I win" issue. You have to remember a few things. Prost crashed into Senna the previous year at the same race to win the championship. Watching the helicopter footage, as well as Prost's onboard footage and comparing his entry into the chicane from the few laps before to the lap the incident happened, he clearly turned in early before he hit Senna and was on trajectory to completely cut the inside of the chicane with all four wheels on the grass. Senna made a very aggressive dive, but Prost closed to door way too late and caused the collision.
Senna rejoined the race, pitted for a new wing, dropping back to 2nd, and rejoined with three laps to go. He hunted down the leader and passed him at the exact same chicane entry where he attempted to pass Prost. Senna won the race only to be disqualified for cutting the chicane -- which as Ron Dennis showed in an appeal, was done by several other drivers at a particular race earlier in the decade and no penalties, fines, disqualifications or anything whatsoever were handed out. Senna was fined for dangerous driving and lost his super licence soon after for challenging Balestre and the FIA.
Now in 1990, before qualifying, Senna, with the support of Prost, argued that the pole position grid slot should be moved to the clean side of the track. The stewards agreed and Senna then won pole. The FIA president, Jean Marie Balestre, rescinded the stewards decision to move the pole and Senna started on the dirty side of the grid.
The rest is history, and here's a quote from Senna himself to sum up his thoughts on it.
"If you get ****ed every time you try to do your job cleanly, within the system, what do you do? Stand back, and say thank you? No way. You should fight for what you think is right. If pole had been on the left, I'd have made it to the first corner in the lead, no problem. That was a bad decision to keep pole on the right, and it was influenced by Balestre. And the result was what happened in the first corner. I contributed to it, but it was not my responsibility".
Whether or not you still feel the same about his actions, that's fine. But there's so much more to it than Senna taking out Prost "for personal gain."
