New keyboard anytime soon?

I am posting this here because I am currently deciding whether or not to purchase a new Apple wireless keyboard. I recently received the new Mighty Mouse as a gift and wanted to get a nice wireless keyboard to match it for my entertainment set up. The current aluminum keyboard was first released in 2007. Since Apple just released their new wireless mouse, I was wondering if they plan on doing something similar with the keyboard.

Anyone know about a new model coming out soon?

Thanks
