1: We have new software that is all ready to go. The software isn't really the hard part, it's more about operations and making sure it runs smoothly.
Does your software have the same features which made people continue using MtGox despite all the problems? Like APIs over multiple protocols, better than all the other exchanges APIs combined, and and multi-currency trading within the same orderbook?
Not sure on the specifics yet. It's fast and secure though.
