I think you're being WAY too optimistic ...
Everybody's Golf 5 (a sequel to a highly popular series in Japan) only pushed sales of the PS3 to the 40,000 range. CC:FF7 pushed the PSP (a system which is more popular than the PS3 in Japan) into the range you're predicting for the PS3 but it required the help of a highly popular re-model for the PSP ...
Without a major change in the PS3 the best these games will do is push sales inot the 80k to 100k range.
