ReadyNAS State of Union?

I've been a big fan of the ReadyNAS -I have one X6 still chugging along. I appreciated that the products generally were on the leading edge for years. But it's hard for me to continue supporting ReadyNAS as the Ultra line is coming up on its 2nd anniversary - too long to keep the prosumer niche waiting on something with faster connectivity. Where is thunderbolt? A few competitors have it already. Not even a USB 3.0 in the Ultra 4 or 6 yet? And then some key employees departing... taken all together it is very disappointing. I suppose Netgear just doesnt see their acquisition of Infrant being all that strategically important and so it is just milking what they can with no investment (probably why you have some employees leaving - out of frustration). I for one cant wait much longer. Anyone have a good suggestion for a replacement NAS?
