Yep, as stated, CCU kits were not released for the Ego9 (or the Geo for that matter).
The CCU kits don't sell in quite the numbers you might think, and in order to keep prices down (both in terms of production and anodising), Planet have to have a lot of kits made, and have a lot of each colour that is produced. It all adds up to a big investment.
When it was made clear that the trigger and reg collar would not be included in the CCU kit, many people expressed the opinion that they would rather get their own parts anodised than have a kit that ended up leaving their marker with parts that didn't match. In light of that, and the amount of money that would be tied up in kits that wouldn't sell well, Planet decided not to go ahead with CCU kits in 2009.
