Big shocker here......well for me anyways, so WOOHOO
The Mulan 2-disc SE DVD for R3 (MAS/BRU) was released 3 weeks ago at the usual price of RM71.90 (or USD$18.80). Purchases at the usual chain stores come with a 10% discount. Nearly all the features listed on these forums are there plus a few additional extras which I guess could only be available on R3 discs or are yet to be announced in other region versions.
From what I could see (heh heh...I have yet to purchase it
) a few extras include:
 New full length music video in Chinese sung by Jackie Chan
 Music video for "Reflection" sung by Coco Lee in Mandarin
 Dubbing in chinese includes the spoken and sung voices of Jackie Chan and a few other Asian celebs (similar to the over-the-air broadcasts shown on Disney Channel Asia)
 Disc 1 features 4 audio tracks in English, Mandarin, Cantonese and Thai (all Dolby Digital 5.1) and what looks like a commentary track?? (Have to confirm this later) Subtitles in English, Chinese, Traditional Chinese, Thai and Bahasa Indonesia.
 Disc 2 either features language dubs or subtitles for included features (once again...will have to confirm once I buy it
 Cover is similar to the one on Amazon but with the words "2-Disc Special Edition" on the top bar instead of just "2-disc set"
So....its pretty similar to the HK release except the cover is in English. Menus are in English to as far as I can tell.
Will update ASAP.....need to get my hands on some $$ NOW!!
