Orangewheels:I think Lambo may come to regret this when they see the sales of the Panamera, or maybe Porsche had a say in it being dropped?
Well, there's an issue over just how profitable anything beyond supermini territory can be in the current marketplace. Lamborghini is still a tiny company (compared with Ferrari for example), and the titanic sums required to develop a new mass-market car like the Estoque need to see the maximum possible return on investment to be worthwhile for them - this isn't a company who can afford to develop a whole new car just to keep them afloat through a bad patch. The thinking may well be that they need to hold back and launch the car after the recession when they can reap maximum profits from it. Assuming that the recession does have an end, of course...
Until then, they can keep developing the Gallardo for much lower cost and benefit from the already-advanced development of the Murcielago replacement.
Chances are this has nothing to do with Porsche - Wendelin Wiedeking feels that Lamborghini and Bugatti should start making "sensible" cars, like the Estoque (which could have been fitted with the V12 and priced £100k away from any four-seater Porsche if internal competition was an issue).
