I'm really really looking foward to trying out JetBrains IntelliJ with Ruby extensions.

Having been a massive fan and customer of Resharper for .NET since day #1, I just know that it's gonna be great.

JetBrains make wonderful tools IMHO. Can everyone please beg them to make us a nice .NET IDE ASAP that works on Linux, Windows, Mac etc. Of course, it will have killer features revolving around NUnit, NHibernate, Spring.NET etc :)
