Jens has got one of the most realistic way of dealing with hardware making for the amiga and dealing with the scene than any other company or person I know of..He has always more than one project going and never rushes into anything, that's why he's also pretty carefull when giving dates of things to come etc.
I mailed with him this winter and he said the project (a600 acc.) was going fine but that he had so much to do that it would'nt be finished right away, then later he gave sort of a releasedate for the accelerator, supposedly for release this summer. This isn't happening i'm pretty sure, but I would guess it will be released within this year.
OFCOURSE, there is a chance it will never be released.
I know for one thing that Jens does not like to get e-mails, forumposts or chatroomquestions twice a day on the matter of when his projects will be finished; as he said to me in one of the mails I (almost regretably) sent him, "answering mails etc. just makes the projects go slower".
So the best thing to do would be to wait and see, like always
