The DTP-70 will also be offered (NOT discontinued).
DTP-70 will be discontinued, they are just waiting for the release of the iSis.
I visited the X-Rite booth today at Photokina and spoke to a former GMB rep.
Basically all X-Rite instruments will be replaced by their GMB counterparts. The second release of the iSis (expected somewhere in December) will have a removable UV cut filter.
