Sony line up gap

With the upcoming A7xx on the horizon, other brands will have a new competitor ( Nikon D300s & Canon 7D ) = one gap filled by the A7xx, but there will still be a gap in Sony's line up IMO, especially when the Nikon D90s launch normally in March 2010, even now the A550 is a little underneath the D90 in feature's, so Sony should better start working on a A6xx , and this time without the feature's that the A5xx should have had, like MLU et cetera..... video...., what do you think??
