A fellow member of PLUG has found out an interesting Brickshelf folder, with some new pictures of the upcoming Linear Actuators. They're a bit blurry, but nonetheless provide a lot of information about this speculation-stirring part!
The new Pole Reverser can be seen too, but in my opinion these images don't add much to what we already know about it.
Here they are, for your "image dissection":
So, the LA's we see on the 8294 Excavator and the 8295 Telescopic Handler are actually comprised of two parts: the LA itself and a mounting bracket (click to enlarge and compare the details on the two upper images).
Also, I'm happy to see that, unlike what I commented on the previous LA-related post, this new piece does indeed have an axlehole instead of a short axle. LEGO has adopted this design on modern motors, and it's indeed more flexible than having a fixed-length axle protruding from it.
So, with the optional bracket and the axlehole, LEGO created what appears to be a very useful piece, with lots of applications in sets and MOCs.
However, there's still the issue of strength under loads (which, being this piece intended for what it's intended, will surely be considerable), but that's something that, as soon as the first sets hit the stores, shall be discovered. And, when that happens, you'll for sure read about it here at TechnicBRICKs .
