UFC 124 RECAP: GSP WINS, now what?

Okay so that's my recap on the GSP/Koscheck fight.  I know it's not much but i did it quickly.  The main reason is now that we've seen him beat 8 in a row, do you think there's any fighter out there in the Welterweight Division that would give him any competition?  If so, WHO and WHY?

I wanna know what do you think GSP's weaknesses are or do you think that he's unstoppable?
Do you think he should move up a to middleweight?
Do you think that he should to a catchweight fight with any of the middleweight fighters?
Do you think he has a chance, if moved up to middleweight?
What do you think DANA WHITE will do with him, now that he's beaten mostly all the contenders in the welterweight class?
Should Dana, force a catchweight bout for GSP?
What do you think of GSP's fighting?  A bit on the safe side?   - he has yet to finish anyone by KO or submission...
