Not to rain on your parade...but all the E3 demos were running on PC gear afaik - generally many times more powerful than even next gen console specs.
Remember that glorious BF4 demo a while back? Yeah...dual 7990 and liquid cooled i7 PC rendering at 3K. In a couple years time that will be in reach of normal PC players. For console player that will be in reach round about 2023...when the console gen after this one hits.
Consoles have their place - mainly for convenience and "it just works". To pretend that they will ever be on par with PCs performance wise is insane though. The business model alone precludes the possibility.
