Few notes:
1) ToV wouldn't work on a Wii. If the Wii had the graphical ability, why didn't Namco port Eternal Sonata to the Wii instead of the PS3? I mean, the Wii would be the vastly more understandable choice for a JRPG in Japan....Unless you'd have to re-do the entire game and scale everything down.
2) Length is always questionable in JRPGs. Eternal Sonata promised a 30hr quest....But was 30 with sidequests. Blue Dragon was 40hrs (or less, depending on who you talked to)....But it was 40 if you ran through everything, and did no sidequests. I think we need to wait for more reviews, and a few players to go through it to determine the length vs. what a few people are saying...Personally, 20-25hrs is too short for a RPG for me, but we'll see. Most older JRPGs were that short.
Back from the dead, I'm afraid.
