Being able to set an electronic groupset to run with any 10, 11, 12 speed cassette really is a game changer. Too bad they don't make rim brake levers, they would make a killing from people upgrading old bikes.
Then wait for the Wheeltop EDS TX. Same flexibility as LTwoo's groupset, but it's fully wireless, better weather proofing and it's available in rim brake. SRAM's patent on wireless derailleur communication is expiring this month. Wheeltop should be able to sell direct to the US, unless SRAM finds a way to block them. Though they use a fixed battery on the derailleur as opposed to removable. SRAM's patent on the removable battery is still in-effect apparently.
