Above link says construction to start this year and take 12 years. So eventually you'll have CalTrain, CAHSR and BART as connected system.
A good point is the projects are being rolled out they way they are due to funding constraints and a desire provide ongoing side benefits, like the electrified CalTrain and the grade separation projects in the central valley. (Every over pass over the existing rail is a benefit).
Also the Phase II BART extension that will take BART to downtown San Jose, the high speed rail station at Diridon and to Santa Clara.
