Will New Canon APS-C Cameras Fix a Big Problem?

Canon has always had a big problem with their Canon APS-C cameras. Maybe I should instead say that it's a small problem, right? If you've been shooting for years, then you probably know exactly what I'm talking about. Canon APS-C Cameras have had a single, nearly lifelong problem since Canon EOS started. And now that it seems like even the Canon EOS-M system is dead, the company has a chance to start anew. But will they actually not mess this one up?
