PS3 or Xbox 360

Current Situation:

• I have lots of Japanese PS2 games, some of which I'd like to play again
• I'm not game addicted that much, but occasionally want to play some popular games like Final Fantasy, Dragon Warriors etc.
• I have lots of Japanese DVD disks, region-2 coded.
• I have Mac mini to play videos and music. No need for another media center solution.
• Don't know if I can turn Mac mini to region-free. Rumors say I can disable DVD auto-play and use VLC to mount VOB files directly.
• Mac mini allows me to change the region code for its DVD drive upto 5 times or something.
• I have PSP
• I'm usually ok with the standard DVD quality when I watch movies at home, but would love to buy HD-DVD or BD if I really like it. Maybe a couple of them an year.

Assumpitions:

• No Japanese PS2 Games on US PS3, since they are region-coded
• Playing Japanese PS3 Games on US PS3 is fine since they're in the same code
• same for Blur-ray Disk (BD) since US/JP are in the same code

So my current choices are PS3 and Xbox 360. No Wii at this moment sir. Wii is for a party and my home is not for that.

Xbox 360:

• Good amount of game lineups. (+)
• Some games have region codes while others are not. (-)
• Upscales DVD to 1080p (+)
• extra HD-DVD drive with $200
• It has a media solution if I have a Vista PC, which I don't have nor need
• region 2 standard DVD not playable (-)

PS3:

• Good amount of game lineups. Less than Xbox360 at this moment but will grow (+)
• Promising big titles like FF, DW (+)
• Upscales DVD to 1080p (+)
• Built-in BD (+)
• PSP integration to some extent. I'm not sure what I can do with it though.
• DLNA support to make it a media center, again which I don't need
• Japanese PS3 games playable (+)
• Japanese PS2 games NOT playable (-)
• region 2 standard DVD not playable (-)

So clearly PS3 wins. The only downside is the region code about PS2 games and standard DVD. Then I came up with another idea:

PS3 (buy in Japan and bring/ship):

• Japanese PS2 games playable! (+)
• region 2 standard DVD playable (+)
• US standard DVD not playeble (but I have Mac mini to play that)
• US PS2 games not playable (but who cares?)

So it looks like a brilliant idea. Wondering how and if it's possible at all.
