Do the new macbook pro models (2011) still have a 4 partition limit?

Question

If I remember correctly, the older Macbook pro models (pre 2011) had a 4 partition limit: so, if you tried to install multiple operating systems, you had this limit.

Do the new models (2011) still have this limitation? I'm planning to install two Linuxes, A Windows and a Mac partitions to boot.
