I checked to see what progress has been made in building that extension. No evidence of construction at the Pittsburg / Bay Point station. The track configuration, for reference, from west to east:
Bailey Road bridge
Bridge over a creek
Access area for road-rail vehicles
Ramp for road-rail vehicles, east end at ground level
South-side track splits, making center track
The north-side, center, and south-side tracks continue for a bit, then end at bumper posts
Next stop: A wider Highway 4 - ContraCostaTimes.com
The highway widening should be done by 2015, and the eBART line by 2017.
Pittsburg puts more money toward future BART station - ContraCostaTimes.com
They are currently planning to build stations only at the ends of the line, but if Pittsburg officials put up enough money, they'll get a Pittsburg station in addition.
The $462 million eBART project is expected to be completed by the end of 2017. Work continues on a transfer platform east of the Pittsburg-Bay Point station and a parking lot and maintenance facility east of the Antioch site.
I've found it hard to find much on that, even at BART - East Contra Costa BART Extension (eBART)

Contract 04SF-110-A - Transfer Platform and Guideway
This contract includes guideway preparation; modifications to the existing BART tail tracks at the Pittsburg Bay Point Station; construction of a Transfer Platform for passenger movement between the eBART and BART trains; and an Ancillary Building with train control equipment. This contract is currently under construction.
So there'll be a BART - eBART transfer platform at where the tail tracks are now.

- about Phase 2, likely extending in Hwy. 4 to from Antioch to Byron / Discovery Bay. The nearby Mococo Line is a less likely route.
The RFP document for the vehicles specified the purchase of 8 "new Service Proven, lightweight low-floor DMU railcars or vehicles" "ready for Revenue Service", with one option for 2 more, and one for 4 more, giving a grand total of 14.
