the Public Test Server has been turned off so PGI (the developer) can make changed based on the feedback they have received.
they are working to update the build for the PTS, we have not yet been given any information on what the next build will be, and again that new build will be subject to change based on player feedback.
at current we do not know for certain what will end up being implemented into MWO, and while PGI are targeting a March patch release, it could still be April or May depending on how long it takes to get to a point where we (the bulk of the testers) think it is an imporvement over the current system.
it is very likely (but not certain) that the 3 Mechs to master requirement is gone, it is also very likely that some sort of cbill cost for mastering a Mech will be there, however I am hoping it ends up much less than the 9.1 million it was on the previous build.
as for reasons to own multiple varients of a chassis, some Mechs have minimal diferances between their varients, e.g. the Crab, all varients are pretty simular, ok, 1 varient has Jumpjets, the others do not, but otherwise the diferance it the position of the energy hardpoints and the base equipment,
while if you look at the Spider the 4 varients each have rather diferant loadouts,
the 5V can mount 12 jumpjets (none of the others can mount more than 8) but can only take 1 large or 2 small/medium lasers,
the 5D has an ECM but pays for it with a lower engine cap, and can take 3 energy weapons,
the 5K can have 4 machine guns and a laser
and the Anazi can have 2 energy weapons, 2 balastics, a missile and 2 AMS
(none of the others can mount more than 1 AMS, or missiles)
so you have one which is more mobile (5V), one which is more stealthy (5D), one which works great as a harrasser (5K), and one which does not know what it wants to be and is no fun (anazi).
some chassis are more like the Crab, with little diferance between varients, while others are more like the Spider and have significant diferances between varients, under the new system (assuming it does not change too much) I will probably master 1 Crab, 4 Spiders (two 5Ds, and one each 5v and 5K), there are several chassis I will want to master two varients of and a few I will want to master 3-4 of.
after the new system comes in Mastery Bundles will no longer be quite as useful as they have been, but still you are effectivly paying for 2 varients and getting 3 varients + premium time and cockpit items, they will still be a reasionable deal
