well, I found another post, made by a blog inside globoesporte.com (the biggest sports portal in Brazil) about the Senna content. It contains some odd things I'll point out below:
http://globoesporte.globo.com/blogs...t/senna-na-lotus-no-kart-e-no-video-game.html
"Já está confirmado que a próxima atualização do game, ainda sem data definida, trará o Ralt-Toyota RT3 que deu a Ayrton Senna o título da Fórmula 3 Inglesa em 1983."
"It is already confirmed that the next update of the game, without a defined release date, will bring the Ralt-Toyota RT3 that gave Senna his British Formula 3 championship in 1983."
"Algumas das McLarens pilotadas pelo brasileiro também deverão estar disponíveis, além do tradicional circuito de Interlagos, na versão já com o S do Senna, adotada depois da reforma realizada para receber o GP do Brasil de 1990."
"Some of the
McLarens driven by the brazilian may also become available, as well as the traditional
Interlagos circuit, in its version with the turn named Senna's S, adopted after the renovations that took place before the 1990 Brazilian GP."
Now, I'd take this with a pinch of salt. This may be due to the rampant speculation we've seen here at GTP (myself included), but Globo is a company that not only is trustworthy, but it is also one of the biggest and earliest partners of the Ayrton Senna Institute.
But what I found most odd was his statement saying that the Ralt F-3 would come in a later update. I believe this might be referring to the car's availability in the Dealership, which means that at least for now we'd only be able to drive it inside the Senna Challenge.
