NoRules looks a lot like the Haywire...
It kind of does. I think I like it though. Any ball with that shade of green catches my eye.
The Wreck-It is going to have a lot of shelf appeal. To me the picture on the USBC site looks like the black is a pearl colorization, but like bowlingman817 said with the Hectic still in the lineup/the newest HP2 ball that would be an odd next step.
The Power Cell is purple, pink, and black. Looks like a solid, maybe polished, to me as well. I'm thinking that may in fact be an international release. Interesting that all three of the new additions have black as a part of the color scheme though.
That was my thoughts as well. If these are all they're coming with then I'm going to jump back to my consideration of the Paradox balls, the Snap Lock, or the Dark Legend.
Don't confuse looks with performance. The No Rules should definitely be a heavy oil option for Roto Grip. All they have in the HP4 line right now is the Eternal Cell so a new flagship piece is needed. The Haywire is still around but being a HP3 ball (and the pricing that goes with that) it doesn't have quite as much potential to be a cash cow for them. Have patience until more info is out.
