A very interesting article today in WTT about the progress with Landa.

Seems to show lots of progress but they sneaked in that the beta testing will start in the second half of 2015. This is basically another 6 month delay from what was stated in the past article from Printweek in the quote above.
I am interested at how this latest story will be reported in Printweek, since they tend to be more comprehensive in reporting and commenting on stories. I am sure they will pick up on the delay.
Additional info.
Here is the Printweek article that I expected.

Sure enough, they did comment on the added delay. They also supplied more info on the cost of development.
