I wonder what could possibly come out while we wait?
well, if the rumour about the gen 3 remakes ends up being true (which is quite possible seeing as it became a trend since fr/lg) then it would make sense for the next gen to take about 2 years to be released. one year for the remakes, another one for the new gen.
anyway, the remakes would be almost guaranteed to keep the 5th gen graphics and mechanics. it's been that way since fr/lg so i wouldn't expect anything other than that.
