I pre-ordered the LE from AmiAmi and looking forward to it. As for the DLC, I will likly not bother with the PS3 DLC, simply because I use it to record the videos, and I can get better quality videos from the Xbox (HDMI caps Vs compoenent). I like AmiAmi becuase theres the chance of the shop exclusives, which they get as there local, where as yesasia and play asia are not.
On the subject of porting, I know they said its a total remake, but the original arcade imas hardware was a modified PS2, no idea if any of that is usable or not however.
The region locking dosnt bother me much as my PS3 is an NTSC-J Asia model, so unless they lock the JP edition to JP consoles, which is very unlikly, it shouldnt be an issue. No idea how i'm going to play the BD, can't remember if its the same region or not Singapore -> Japan.
G4U may well end up on the PSN as well, I doubt the *only* way to get it will be with the anime, that seems a little too limited, and it would limit them to the Anime's sucess.
As for the PS3 ver in general, i wasnt surprised, they have had the imas store on PSN for SP, and the SP stuff in PS Home has been there ages and was still there a couple months back, I not looked recently to see if theres anything new, hope there is or will be. Anyone been to Namco's area in Home recently?
