No details yet, just that it's coming and Capcom is releasing it. http://wireless.ign.com/articles/990/990875p1.html
Unless they do a REALLY poor job translating this, I am so there. This is probably my favorite shooter of all time, and I still play it when I can find an arcade that actually has it.
This was one of my favorite games back in the day and on my mobile phone. It should be even better on my iPhone. This is going to make a nice addition to my collection of shooters! I can wait for this release!
