XLs will be in the works, right after the holiday. I'm considering big batts and mega cartos also, but I'm still testing those. Fillerless cartos are a bit further away, but are definitly in the works.
I was strongly considering getting the CE2s, since I was the one who originally asked Martinez to come up with a burn-proof cartomizer, leading them to create the CE2 in the first place. But in the end, they still have too many problems, and I just didn't have that much confidence in MicroCig's quality control, compared to our MaxxFusion manufacturer.
Fortunately for me, the chief engineer at our factory doesn't let any dust gather on him, and is always working on something new, and his current project is a different design of fillerless cartomizer that I am confident will blow the CE2s away, just like our regular MF cartos blow away other KR8s. Still in the prototype stage, then will need testing, but it will be coming, and it will be another MaxxFusion exclusive!
