I don't think so aces... Keep in mind who is behind the project... Same people who developed and delivered Far Cry... The game which made every high end generation card of its time crawl... Thats what i believe will happen this time cause Far cry has made enough goodwill for the game developers and don't forget the hype which crysis has generated...
Also the last engine which scaled really well was the Source engine.. And the reason for that was that multi player angle which the source engine had to encounter... While crysis will have a multi player setup also but its USP is the physics engine with awesome gfx which only a high end card will be able to handle... But then again thats the way i think... And i can definitely be wrong
