Nah. I've seen etap have all kinds of problems, and SRAM's QC is, simply put, shithouse. Needing multiple small, short life batteries is a hassle too. One of the best things with Di2 is the ability to just forget about the battery for months, and then charge quickly whenever you remember. I've already been seeing the new 'ultimate' pike's failing (ingesting air from + to - chamber). That, coupled with the unpredictability of eagle to do it's job is enough for me to avoid it.
I imagine we'll see new Di2 later this year, possibly with a wireless shifter and wired main battery/computer to derailleur.
