I can only think of one reason, you can sell your Legacy 990 set for a pretty penny right now and pick up a BASE3 with money left over in your pocket. But that's about it.
Now for those who are getting started vs. many of us who are established with a CAB-1 or CAB-2 system, I can see the BASE3 & CAB3 app being a natural building block as you progress through your first R-T-R set with Bluetooth and eventually building a larger roster of more engines with Legacy and LC2.
For the established crowd of CAB-1 & CAB-2 users, there just isn't much there. You essentially get a CAB-2 with PDI connectors and a WIFI module built in with a "new" module that allows interfacing to previous RF & Bluetooth engines. If Lionel would have just made that "new" Bluetooth module available as a stand alone product to operate on the LCS bus, folks could essentially build the BASE3 al-la-carte.
Regardless, the new CAB3-L app will work with older BASE units that have the WiFi module attached already and if I understood Dave Olsen correctly the CAB3-B part of the new app will communicate directly with (3) Bluetooth engines without any BASE or LCS components. So even without the "Bluetooth & RF" module of the BASE3, your CAB2 system (with a Wifi module & CAB3 app) will do everything the BASE3 & CAB3 does (minus control of RF engines.).
