iPod Touch Refresh?

Apple didn't release a new iPod Touch this year (except for the 16GB 5G, which is not really "new"). Do you think they will release a 6G on October? Or do you think it will be scheduled next year?

If you think it will be released alongside the iPhone 6 next year, do you think it will get a huge bump to A7 from its current A5 (and A8 for the iP6) or will it just be bumped to the A6 (which will make it two generations behind)?
