I'd wait. If they don't announce anything at E3, then just go with the Asian version, which has full English voice acting and text.
And keep in mind, the game is incredibly hard, so it's not going to be everybody's cup of tea.
And I also didn't think it would be this good. When it was first announced, I was like... RPG? From From Software? Enchanted Arms? Meh.
Then I saw the TGS footage, and that made it look even worse. In the demo, the main character was clipping through things left and right. He walked straight through a rather larger wagon wheel at one point. It was laughable.
And then the game came out which lead to nice reviews from Dengeki and excellent word of mouth from Japanese players and importers on neogaf. That's around when I had a big reversal in opinion and became totally stoked about the game. The Soul Network sounded cool, the combat system looked right up my alley, and I loved the whole medievil feel of the game.
Edit:
By the way, I hated Oblivion.
