For me it's obvious that he no longer interested on boxing, and that's why he was been out for 2 years. His injury really did it for him because when he come back, it was a different Thurman, his power is no longer there and maybe just boxing around for the money. His lost to Manny already proved that his motivate and fire might be really gone and after that he was on/off in boxing. Obviously he can still run his mouth in this fight, but as far as performance, Tszyu being the younger and the champion might have the advantage here. Let's watch here the kick-off press conference:

I guess Thurman has mastered the art of thrash talking, It is good for the fight, boxing fans want to see action and a lot of talks in the press release and Thurman can provide that and this will sell the fight.
But of course, fight fans want to see action so it is very interesting to see how both fighters will react to the earlier thrash talk can Thurman that Tszyu is slow and flatfooted, and can Tszyu chase and eventually knock Thurman out?
It's still a month away but we'll see more thrash talks coming from both parties.
