Does anyone know anything about theses irons or when they are supposed to be released for retail?

I've been looking for those answers too.
Basically in a few months, but it seems most people are saying late May early June. I talked to a Titleist rep a few weeks ago at a demo and he gave me several answers starting with August then he said July... I got the feeling he really didn't know. Searching several chat rooms people tend to say early June. BUT knowing how Titleist pushes release dates back like their new woods from March to April – who knows. Another point is Titleist hasn't started to market the clubs and usually they promote the new stuff a month and a half ahead of time. I emailed Titleist and they only said that anything new will be posted on their site.

OK.
Tech info on the clubs. The rep told me they are not true bore through irons like Callaway stuff. They look like it, but it's just some wieght removed from the heel then relocated and then they filled the hole with some sort of black material.
They are stainless steel forged and acording to the rep are comparable to the 690.CB as far as playability
