That definitely seems to be the case, so that's another thing which makes me hopeful SGRAs are just late, but still in the works.
There's no reason to believe that's not the case.
I think some SGRA naysayers hope that the end of this year is some magical cutoff for the possibility of adding SGRA's and if they don't drop by then, they will never ever be added!
The new WZ is late.
The Cathar race was hinted for this year. So was Makeb. I think even HK was later than was earlier expected. They've stated that the F2P feature didn't mess with their other release schedules but I doubt that's the case (though, it probably will only affect it by a few months).
