No updates on the immediate horizon, the beta of 1.0.4 will probably come out at about the same time as 2.0pr1 (the first preview release of 2.0), and at the moment I'm making absolutely no promises whatsoever about when the latter might be available.
But in regards to lmcjipo's question, we do indeed plan to make it possible to run 1.0.x and 2.0 on the same system without having them interfere with each other - we did this same thing with Oxford Dict 2.x and PlecoDict 1.0 and it generated a lot more useful bug reports / feedback than we would have gotten if we'd forced people to give up the old software to get access to the new.
