EE now has these up for pre-order,
Set #1 includes (subject to change): R3-T6, R3-T2, R2-C4, R4-A22, R2-Q2.
Set 2 includes (subject to change): R3-Y2, R2-M5, R2-A6, R4-E1, R2-X2. The only ones I'm really looking forward to are R4-E1, R2-X2, R2-Q2, and R4-A22. At $40 a set it's rather spendy, but if you're a droid freek like me you'll have to get them!

What are your thoughts about these sets, Getting them or Not?
