Best Gaming Keyboard? Should I Wait?

I was looking at the the g15 logitech keyboard and i was wondering if i should get it or wait! Or get another keyboard. Can anyone recommend a good gaming computer? or can someone tell me if i should wait till the next logitech g keyboard? Can sometell me what the next logitech gaming keyboard is going to be?

I would go with this keyboard, it has better reviews than the G15-http://www.newegg.com/Product/Product.aspx?Item=N82E16823126009As for a PC, try this-http://www.newegg.com/Product/Product.aspx?Item=N82E16883227081
