Lego Star Wars I and II was available for last gen consoles. So it is not truely NextGen. There are features being added to each port to take advantage of platforms (and give people a reason to buy it) but, it is a LastGen game... There is nothing stopping them from releasing it to other platforms... They have just chosen not to.
As for CSI... You have me there. But, I would venture that this is not going to get very good NextGen ratings... I may be proven wrong but this does not look like the kind of game that is really going to push any console to its limits.
Don't get me wrong, I love my Wii... It is just not an apples to apples comparison with either the 360 or the PS3... Which are very much alike.
