I have purchased Pioneer BDP 450, it has reached me, after intial tests here are my initial impression
1. The player is not sleek, though not heavy
2. It has twin HDMI, digital coaxial, 2 USB,RJ-45 ports, no Wi-Fi
3.it has a front display which is convenient and enough for viewing pleasure
4.Remote feels like a cheap one, its not as responsive as one would expect from a BDP costing more than 10K.
5.user interface is for minimalist, no frills, no way its brilliant, but as I said enough
6.It played both MKV and MP4 fine, it does support both merged SRT and external SRT
7.disc loading time is same as my older LG BD 550
8.disc scanning and REW/FFW for video files are faster than BD 550.
9.on 720p videos Qdeo video processing seems a hair better than the LG BD 550, yet to test on a 540p DVD video.
10.Blu-ray play back is as expected, crisp,detailed
11.It has zooming capability
12. The most important of all "region hack" - The model I bought from ebay.in
Pioneer BDP-450 Blu-ray 3D Player | eBay
has firmware version 2.09. I tried for flashing the FW and installing version 4.04 as suggested in avsforum (post # 77)

The player didn't recognize the firmware provided in the link over there. I tried USB stick, HDD at least 5 times with many file combination and single file, it just does not work. Read post # 87 which clearly says if you have a 450 with FW 2.09 you can't flash it at all. In this regard if someone has done it successfully can explain.
So as it appears now I have to go for a region B player. Hope I helped some of you
