Viasat 2 was launched a couple months ago. It will take 5-7 more months to boost into the proper orbit and complete testing.
Supposedly

Operational by the beginning of the year, it will supposedly allow WIFI over the Caribbean and will ALSO relieve a lot of the traffic from Viasat 1. It will allow TWICE the throughput of viasat1

Viasat 3 will be launched in 2018.
