You people are crazzy!!!... 20years... even 10years... I mean jease Lorren and Sherry will be 'Odd damn' generatrics by then (or at least comparitivly to their fans)!!!
How do you think that any company could deliver such a product over such a huge time scale so consistantly with out going bankrupt 10 times over?
Once they get the swing in to it they will be pumping out a game less then every year...
... The quintology is only a small part of the total Oddworld plan after all and Im sure the people who make it now will like to live to see it end!!! (I dont mean to be overly offencive to OWI, but im trying to stress my point... plus it just comes naturally to me
)
Even OWI must not think that it will take too long to make each game because they still have 4 more games contracted with the Xbox... And the Xbox has only about 4 and a half more years of viable life... And when you consider that OWI has always had a emfisis on having the best technology they will not want to still be part of the Xbox after it becomes low tech... And if they want to get to the top of the game early they will bail out on to the PS3 in 3 years (which they can only do once they met the terms of their contract with Microsoft)...
In other words they will probly finish the quintology in 5years or less. 5years is far more realistic then 10years onwards.
