well...the question is...does this new 20mp sensor have the same moire problems of it's older siblings ?

May be, needs testing. But looking at the specs it uses quite old LSI.

Image quality is excellent, with results from the 20 megapixel APS-C sensor proving the equal of last year's 16-megapixel imager. Noise doesn't really rear its ugly head until ISO 3200 for JPEGs, although the A5000 does apply pretty aggressive noise reduction to keep the files clean, resulting in some loss of finer detail. The myriad of creative effect on offer such as HDR, Dynamic Range Optimisation, creative styles, the innovative sweep panorama mode and the range of in-camera Picture Effects help to get the most out of the A5000, especially if you like to experiment away from a computer.

The A5000 represents a smart choice for anyone looking to enter the world of interchangeable lens photography, but is up against competition from some very capable entry-level DSLRs. Below I compare it to two of its closest rivals, the Nikon D3300 and Canon EOS T5 / 1200D.

This camera is very inferior for video than A5100 and A6000? because look very interesting and inexpensive.

Yes, it is inferior.
