Apple have announced an update to its iPod Touch line, this includes the new 64GB model which will set you back £299.
Prices of the 32GB and 8GB models have dropped in the states to $299 and $199 respectively so expect the UK to follow.
Apart from that there has not been much of a change but it appears that the new models use the same CPU as the iPhone 3GS, since they can run OpenGL 2.0
