I didn't say that they would make it impossible to work with a battery- just jettison the battery out to an add-on (sold separately) accessory... like current useful ports... or headphone jacks, etc. "Thinner" can't magically thin forever without more stuff being jettisoned to- in Apple's own words- "make room." And battery is the biggest space eater inside all of the principle Apple tech. I'm looking at that OWC thing announced this week and I wonder if it is offering a peek at the future, where Apple kicks out the battery and one pretty much must buy a "bottom" for a future MBpro to add in the battery, much like one needs dongles or a hub to plug into the new MB for (what many consider essential) ports that used to be there. For all the passion some have shown in supporting the choices to jettison headphone jack and then many key ports, why not? "Thinner" seems to rule all.
