Retina resolution design...
Are iPhone5 1136x640 & iPad Retina 2048x1536 resolution widgets under development? I assume yes, but was wonder if an ETA existed. target running on the devices. Comparison - in proto.io you work within the native iPhone5 retina resolution for design and not the 2x aspect. There output looks great running as home screen'd safari app.
I am about ready to chose Prototyper for our project, but need a clear answer on this.
