Yes,
Now all QFR come with black top covers. At this point, we have flushed out all inventory of Black & Brown switch in most tier 1 (NE & Amazon)
As for blue switch rapids: We still have a little bit of QTY in a couple of Amazon's warehouses that have silver/grey covers but that should be flushed out this week. So as for blue switch, its a little bit of a gamble for which top cover you will get but that should be all cleared up by EOW
