Indeed. 6 weeks to go and we're still yet to see anything particularly newsworthy about GT7. Graphical improvements were a given with new hardware, everything else seems to be returning content that they cut out of GTS for whatever reason, other than new cars which again, are a given. Nothing PD/Sony have shown so far of GT7 has surprised or excited me. Sure, dynamic time/weather and more customisation is nice but it's not new, nor are the tracks. It's hard to get massively excited about giving me something back they took away, even if they have improved it.
GT6 promo material offered driving on the moon, Goodwood Hill Climb, GPS Course maker, new tracks like Silverstone, Brands Hatch, Bathurst. Sure, the moon stuff was nonsense and the course maker never lived up to promise even 18 months late, but still. It was new content.
So far with GT7 it's GTS + old stuff, incremental updates where you'd expect and minor things like GT Cafe.
When people are citing dirt flicking up and instant loading as things to be excited about you know there isn't much to go on.
