The recent volume of The Journal of Halacha and Contemporary Society has a nice article on this topic.
From the soft matzah website:
HaRav Weitman, the respected Rav of Tnuva wrote, “I requested that an associate take the Matza you left with me to Rabbi Elyashiv. Rav Elyashiv saw these (Exodus) Matzot and inspected them, and he said that from what he observes, these Matzot would be perfectly Kosher for Pesach.”
this is the email I received from Rav Weitman
“???? ???? ???? ??,
?????? ???? ???? ?? ????? ?????? ?? ??? ???? ???? ?????? ????”? ???? ?????? ??? ?? ????? ???? ?????? ?????? ???? ????? ????? ?????? ?????? ???????
In response to a subsequent inquiry, Rav Weitman added that
“???? ?? ???? ??? ?? ????? ?? ????????”
“I am positive that HaRav Elyashiv said this in relation to Ashkenasim”
