It looks like finally the big manufacturers are catching on to the trend towards lower gearing than their 50/34 compact cranks have been offering until now.
It started with Randonneurs and "Adventure" cyclists riding on gravel. Sugino has offered combinations such as 46/30 with their "Compact Plus" cranks for years, as has White Industry with its VBC (variable bolt circle) cranks. I've been using Sugino OX601D 42/26 cranks since last November.
Last year Shimano announced its Metrea "urban cycling" group targeted mostly at commuters, which offers either a 42T single chain ring or a 46/32 double configuration. Here's an Elephant NFE set up with the double version and hydraulic callipers.
FSA's Adventure cranks, available in several group variants (including FSA SL-K Adventure) come in a choice of 48/32 or 46/30.
Especially when combined with 11/32 road cassettes, a lot of cyclists will be able to get sufficiently low gears with these cranks and a medium cage derailleur, without the need to go to 34/36 cog MTB cassettes and long cage derailleurs.
