@Andrea and other "I didn't have a previous Motif/MO" and also those who don't have backups if they did:
I alluded to this - but did not spell it out. The Motif and MO-series keyboards which Montage v2.0 claims compatibility with (Motif XS, Motif XF, MOXF) all had free sound expansion packs which are still freely available from legitimate sources on the net.
Primarily this includes Inspiration in a Flash - but there are others.
You can benefit by having access to both the voice and performance data of these expansion packs.
Personally, I think it's jumping the gun to assume all of them work without flaws (would prefer to be able to test them out before listing sources) - but here's a few - there are more:
User submitted work (probably didn't have any compatibility issue in the first place, but now presumably you get the performances too):
... actually - no need to reinvent the wheel. This post has a lot already listed with download links. I just checked the first one, some may be "dead":

Adding the Inspiration in A Flash for Motif XF (above is MOXF):
One may feel better downloading from the product support pages:
Maybe there's a Motif XF landing page - didn't find it from a quick search.
... if you didn't backup your data - then it's "lost" of course if you sold the keyboard and do not have backups or the flash cards. If you bought sample packs and sold them (transferred them) to a new owner - then I don't see how it would be justified to expect having your cake (money from the sale which included sample packs) and eating it too (somehow using libraries you sold on your new keyboard). Those at-cost libraries should be available for re-purchase on www.yamahamusicsoft.com
or the sample-house's product support page, or motifator.com under "shop".
Looks like you're going to be frustrated for a while if you stick with Yamaha. I've seen other users complain. The alternative is that Yamaha is silent until the day they release something then dump all the details and the download at the same time. I do not see this as preferable.
The normal process (it's happened many times with Montage firmware and other software releases) is for Yamaha to pre-announce high-level features of new firmware or software and sometimes it's over a year before the software is released. Generally with firmware we may get a month (or less) knowing generally what is going to be released. Sometimes "leaked" out through video demonstrations (like at NAMM before public availability), sometimes in this forum with hints from Yamaha employees or other sources. This gives us consumers a "heads up" that something new is imminent. The full details for firmware are listed in the "_nf_" (new features) document and also in the readme release text file. Until official release these documents, in the past, have not been pre-released. I would suggest getting acclimated to the way these firmware roll-outs generally work and view your firmware requests -- which I know you invest a lot of wishful thinking and effort into -- as suggestions that may never make it regardless of how great of an idea you may have or how big of a flaw you perceive is in the firmware. The test cycle of firmware should be very long to ensure quality firmware -- so the code was likely complete month(s) ago. Your "new" firmware requests need more patience. And some things just are not in the cards to be ever implemented if what you need requires a hardware update (new DSP, new core processor, etc) -- or may be too evasive to expect any solution/enhancement anytime soon.
I do not see these pre-launch announcements as a lack of information -- I see them as additional information I would not otherwise have if Yamaha held their cards close to the vest.
