"A refresh of the EVA line is expected in March with new 6440 and 6840 models."

My EVA roadmap doesn't have anything labelled "6440" or "6840". It does have two other numbers though, but I think they're still NDA so we'll have to play "Guess The Moniker".

The previous models were the 4000, 6000 and 8000, the current EVA range is the 4100, 6100 and 8100, and the first new product in the new range is the 4400.....
