These results are not really surprising. Basically, the question is worded in a way where it's asking a bunch of gamers if they are going to continue gaming on the next system if it is ONLY all digital distribution. Even some who don't support only having full digital distribution are going to cave on this when it's the only option.
I think a more interesting question would be "If you could only buy one console next generation, would you purchase a full digital distribution gaming console over a competitor's console with a disc drive?"
