Last year I was on the list for a G0490X jointer and the backorder date kept getting pushed back. I canceled the order when something came up on craigslist locally. Recently, in September, I ordered a newly (re)released planer G1021x2 (which was made in Taiwan as well) with an estimated ship date 10/1. The ship date was accurate, and the planer arrived on 10/5.
YMMV, but in my experience their availability date on a new product, not an existing backordered product, was accurate.
