So have I ! When is the official news expected?

I'm hoping electronic 11-speed ultegra will be lighter than 6700.

if things go like DA, Ultegra Di2 will be a little lighter than standard. I can't wait for this to come out. Shame is, I just bought my wife a new bike because she damaged her old one (Domane 6 series, w/ Ultegra 6700). I purposely didn't go with Di2, since new Ultegra was due out soon. I guess I'll just have to upgrade her!

Should not be a surprise to anyone. And we'll see 11 speed 105 next year. Shimano's trickle down strategy is very predictable, unlike say, SRAM.

But pics are nice to see. 4 arm cranks too.

Sounds like some nice improvements. I am not super impressed with the current Ultegra.

My Shimano rep told me about this about a month ago. It is nice to see some pics. The crank looks pretty bad, but if the shifters work anywhere near 9000, this will be a runaway success.

I fail to understand Shimano's crank strategy. No BB30, weird 4-arm design, assymetric blades, no 110mm 39T blades, etc, etc.

Interested to see what 6870 will look like.
Presume 2013 Ultegra Di2 will also morph slightly and become 2014 105 Di2?

I hope they make a glossy silver option.

shimano does not do BB30 because they do not believe that BB30 is a superior standard. they have argued this before, and as a mechanical engineer, their argument does have merits. BB30 gives you a tiny and, to a human, imperceptible increase in stiffness for much much higher complexity in maintaining the system. you get smaller Q factor, yes, but that is not a good enough reason IMO. it is, technically more robust to the elements than outboard bearings, but they are a PAIN to replace if something goes wrong. outboard cransk are much easier to replace, more versatile, and less likely to damage your frame on installation. same goes for PF30, and to an extent, BB86 and BBright as well. shimano will also make less money. so I DO see why they would not support BB30.

BB30 is popular among frame manufacturers because it saves them money. it's much faster and cheaper to purchase an OE spec bearing and press it into the fram than having to machine out steel threaded inserts and bond them into frames. it's a simple case of frame manufacturers versus shimano here. but shimano is sticking to their guns and as the major industry player, they have evrey right and clout to do so.

the 4 arm design may LOOK weird, but it offers tangible engineering benefits. the 4 arm design has been on shimano MTB cranks for awhile now. 4 arms are lighter than 5 arms, and shimano claim that the crank still retains the same level of stiffness. in addition, the new 4 arm design makes 110 or 130mm BCD pointless. you can put a 50-34 on that crank. you can also put a 53-39 on the very same crank. this is a game changer. cuts down inventory that stores need to hold ( you don't neeed to carry both compact and standard cranks anymore.) it also streamlines manufacturing. these savings may eventuaklly be passed down to the consumer if enough people follow their 4 arm standard and make chainrings for 4 arm cranks. ( shimano chainrigns are great but exoensive.) the problem here is that most other crank or chainring manufacturers are 5 arm, so they are trying to revolutionize the game here. My feeling is that this is a real game changer. once you get used to the 4 arm design, it actually looks pretty cool.

the new crank is certainly an impressive bit of techy kit and I'll be trying to get my hands on one as soon as ultegra 6800 comes out.
