The 15" retina can do three (and itself) via daisychaining two Thunderbolts (or just using the two ports) and with the HDMI port. Is the 13" retina able to do this as well?

These resolutions were used:
- Retina on laptop @ “best for Retina”
- iMac used as a display @ 2560 x 1440 via Thunderbolt
- iMac used as a display @ 2560 x 1440 via Thunderbolt/DisplayPort
- LG monitor @ 1920 x 1200 via HDMI
Quote from the MacRumors news article on that:
This makes the Retina MacBook Pro the first Mac -- other than a tower-based workstation like the Mac Pro -- to natively power four displays simultaneously.
If it's HDMI 1.4 as noted above, it should support "4k" resolution (4096×2160p24)
