Robot Damashii Exia - early August release, 2,940 Yen (inclusive of tax).
Robot Damashii Crossbone X-2 Kai - late July release, 3,990 Yen (inclusive of tax).
It's explicitly mentioned in the text that this is the second prototype of the actual release, so there might be some changes to be made to it before the actual release.
Also, regarding Tamashii Web Shop limited conversion pack for Exia R2. Apparently there will be a second round of pre-order for this item, after Robot Damashii is out in August. The delivery date for that would be some time in Winter.
