It was made painfully clear that Metal Gear Solid would be the last sequel to the Metal Gear Solid series from Hideo Kojima (the creator) but its been said by konami that Hideo Kojima would not be stopping his career after MGS but there is a new series in the works. The series won’t be released untill the PS3 sales go up in japan because of the usage needed by the game from the console is insufficient at the moment, at the same time Tanaka mentioned MGS Online, that might be something to look forward to as well.
