A quick check at microsoftstore.com shows that the 128 GB/i5 and 256 GB/i6 models are still promising launch date (6/20) ship dates, while the other models are already showing 8/31 shipping.
| 64GB/i3 | $799 | 8/31 |
| 128GB/i5 | $999 | 6/20 |
| 256GB/i5 | $1,299 | 6/20 |
| 256GB/i7 | $1,549 | 8/31 |
| 512GB/i7 | $1,949 | 8/31 |
UPDATED: As far as I can tell, those models were always showing an 8/31 ship date.
