Will the X10 be able to display album art?

It's not clear to me about the SD card. Does it mean it takes 2x 64gb or 2x 128gb cards?

I was looking at buying an X3 as at the moment I have an Sansa Clip + which is tiny. I like my players to have a bit of girth, not too big and not too small. Is it worth waiting for the X10 or should I go for the X3 seeing as it can run Rockbox?
