Yes Lelouch *avoiding eye contact*, correct there, he thinks Luffy will do what it takes to get that fruit but we have yet see whether if he (Luffy) will be really interested in it. My bet is on "No".

We don't know when did Doflamingo actually got the fruit but I am assuming its sometime during the TS, not recently not long ago. If he did found it during the TS and already he have the intention to keep it just for the sake to ransom Luffy, then he's really got one hell of an infactuation on that boy because how can he know Luffy will be going against him in the near future (which is now...)
