Posts like yours are the reason the devs post so rarely nowadays. Instead of applying common sense you pick these posts apart, analysing what the exact wording could or does imply, drawing false conclusions or even promises from it.
Yeah he said that. At that point in time it wasn't clear if they might be uploadable at some point. Or maybe it was just a figure of speech and didn't think twice about it. Turns out Z15 hotlaps won't be uploadable, considering the new physics coming out and all.
If I was a developer that had to put up with this bullshit over-analysing, I'd also rather stop posting altogether than risk saying something that could be interpreted wrong or could possibly not be 100% correct. FFS.
