If the G11 (and the B11 when it comes out) doesn't allow parallel routing, at $799, it's going to be an opportunity missed for Zoom to successfully move its tanks onto Helix territory.
As much a fan and user of Zoom products as I am, I have to agree that they may have a real challenge on their hands with the G11. As you move UP the food chain in cost, the current market indicates that consumers in the $800+ market are much more demanding WRT available features. Parallel path signal routing is one of them, as well as other programming features (like switch assignable "Snapshots" or "Scenes", for example).
At the same time, I fully appreciate that even with the asking price for the G11, there are going to be people who perfer the simplicity of the design for hands-on operation. Time is money, and and Zoom products can usually get you up and running your custom patches quicker and easier than most (perhaps all) other multi-fx modelers, though this seems to be at the expense of higher-level programming capabilities.
I say this while I salivate at the possibility of trying out a Neural Quad Cortex, so don't mind me!
