I've just finished writing up some notes about the new TS-E90mm
http://www.northlight-images.co.uk/ts-e-90mm-f2-8l-macro-review/One of the sharpest and best quality lenses I've tried on my 5Ds. I've even included some comparisons with my old original TS-E90.
Hope it's of some interest - I've now written up notes on all three new TS-E lenses and they are very nice.
My only (relatively minor) quibble is the shortened throw for manual focus from 3m upwards, which make them a bit twitchy for hand held manual focus.
