the US release 日期 hasn't been confirmed. However, reports 显示 that in Mexico and Australia, 你 can pre-order the dvd. However the cover art hasn't been chosen.
I don't think Eclipse will be on DVD until maybe around this fall, maybe nearer to Christmas. It's only been in theaters for a 月 plus a few days. So, it's completely normal for there not to be any news about the dvd.
