Last I heard was fall but that wasn't anything "official" Supposed to get my 2520 later this month and I am planning on adding the 270 at some point in the future.
I just got a 2520 off craigslist. I Hope to put a hoe on it soon.
I hear that the new 270 should let you keep your 3 point attached
It seem that would be a big advantage. I wonder if the spec are the same as the 46.
