This version of Han Solo will be exclusive to set 8097 (Slave I).
Minifigure Parts and Accessories
Han Solo is a rather simple minifigure with only three main parts; head, torso, and legs.
Variants of this figure have appeared two other times. Minifig sw015 appeared in set 7104 (Desert Skiff) back in 2000/01. Back then Han's skin was the classic yellow, his torso print was much more basic, and his signature 'smirk' was slightly different.
Solo came back in 2006 (sw084) on Jabba's Slave Barge (set 6210). The main change was that Han gained his fleshy appearance, but all other details remained the same.
In 2010 we see an updated torso pattern with more realistic touches. Is that man cleavage I see? The facial expression gets some subtle upgrades, including the now ubiquitous white pupils.
The key accessory, if you want to call it that, is the carbonite chamber (aka the real reason you'll buy this set). Previous versions of this part (2454pb02) was a printed 1x2x5 brick. Said part appeared in four sets: 2000's version of Slave I (7144), 2003's Cloud City (10123) and Jabba's Prize (4476), and 2006's version of Slave I (6209). Putting its bricky past behind it, the carbonite chamber is exclusive to this year's updated Slave I.
Although not necessary, the Han Solo minifigure can fit in the back by connecting his hand to two posts at waist level. The chamber also has two handles at each end allowing Boba and Bossk to carry him off to Jabba's palace.
Army Building Potential
The ABP for this figure is low. With many different version of Han Solo available throughout the years, collectors will likely want the updated figure, but not in multiples. Add in the fact that the minifigure is not needed for the carbonite chamber, and demand for multiples is low.
The carbonite chamber is the big draw here.
