As of November 30th, all EQII users will be migrated to a new launchpad.
What's new about it? Well for starters, it doesn't require Flash. It also boasts a "much faster patching speed" and a "general aesthetic upgrade." The migration process should be painless for the end user, as Dave "Smokejumper" Georgeson says that all you'll have to do is point the new launcher at your existing EQII directory when prompted. There's a bit more info on the official site if you're curious.
[Update]: EQ2Wire has a great dev rundown on what exactly is coming with the new launcher.
