Definitely looks like a 'shopped 100mm f/2.8L IS Macro.
They moved the "Canon badge" into the area where the tripod ring goes (note the badge is much wider than it needs to be, as if the word "Macro" had been removed) and then moved the distance scale (it's not from the 100 macro, though) to where the badge had been. They also shortened the area between the focus ring and the red ring.
I remember when everyone called "fake" on the leaked 24-70mm II images as well and it turned out to be real, so I'm reserving judgment at this point and hoping for the best. This is sure to be an excellent seller for Canon if it is indeed real and I know I'll be one the first in line to purchase one.
No you would definitely not get it... I'll make some translation for you.
I've checked out the post from xitek forum that mentioned "135 f/1.8L IS", and...
Here's my opinion:
This is a PS work, if you could read Chinese you would know that.
1. You may find something wrong around the minimum focusing distance, for that "0.8m" was developed from a "0.3m" mark (from new 24-70 possibly?). Several replys in that post pointed out that 0.3m may produce a image that more than 1:1 when shooting macro and suggested that author fix that "bug" in his image:
"最近对焦0.3米？哈哈" = "0.3m closest? LOL"
"介不系人像头，介系超微距" = "This would be a macro photography lens rahter then a portrait lens LOL"
2. Another reply from "F6010" suggest the author add some details on that lens and the author did change his work.
"请LZ参照135L的对焦尺改一下吧，顺道把景深标记也加上 原来的对焦环有点像35L的" = "You may alter the Distance and DoF scale in a way like 135 f/2L, your original work seems like a 35 f/1.4L"
