Here's my album on Pokemon's instruments from B2/W2 - OR/AS, and Colosseum and XD as well. I thought I'd share mine and a few others' findings here since it'd fit.
I must note that I'm still not sure if MOTIF is used for Colosseum/XD. Likely not. XD appears to use Cinematic Strings, and a lot of Colosseum's sounds are from Halion and E-MU Proteus.
Hitomi Sato is often a user of ETHNO WORLD. DP sounds are from Roland's SC-?? (I know the sounds are in Hyper Canvas and someone mentioned it a while back)

Stylus RMX's "Find the Exit" preset is used in ORAS Rayquaza Battle theme
Stylus RMX's "Tower Zero" is used in two themes, "Oceanic Museum" and "Explosive Situation! Red or Blue?"
"Two Speeder" has been used in 3 tracks in Generation 6, one being Minako Adachi's "Dark Skies" in XY, then Anistar City of the same game and composer, and Mt. Pyre from ORAS... of the same person.
Stylus's "Eclipse" loop was used in ORAS's Team Magma / Aqua Hideout theme.
Addictive Drums was used in the ORAS trainer and Elite 4 battle themes, along with XY's trainer, and wild battles.
Addictive Drums was also used in a number of XY overworld themes, and ORAS, including Slateport City and Battle Resort. Since Kontakt is usually common with AD in Shota Kageyama's music, I might as well mention his "signature" sforzando brass from Kontakt's factory library which was used in themes like ORAS wild battle, XY Route 2, ORAS trainer battle, ORAS battle resort, XY Gym Leader Victory, etc.
In Go Ichinose's game "Sotiri Horse", Addictive Drums is of frequent use along with MAGiX Independence (formerly Yellow Tools) for pop brass and saxes. EWQL Symphonic Orchestra Gold is used quite a lot by him (from what we can see in Sotiri Horse, and the B2W2 title screen which was streamed audio composed by Ichinose).
Hitomi Sato is a user of MAGiX Independence, in themes like XY Geosenge Town, it's acoustic Spanish guitar preset can be heard with EWQLSO's oboe. She also used Hollywood Orchestra/Woodwinds as evidenced by XY Courmine City's saxophone.
Ichinose and Sato are very frequent users of Stylus RMX. For example, B2W2 Hoenn Gym Leader battle is Stylus's loop "Yellow Funk". B2W2's electric guitar is from HALion 3 if I'm not mistaken, and the PWT theme has a loop from Stylus. And Colress's battle theme. There are a lot, I'll have a list done soon.
XY Team Flare Battle's lead synth is from Halion 5/SE 2, labeled "Pinched Typanium" or something like that. I don't have the Cubase demo anymore...
Shota Kageyama uses a lot of AD and Kontakt, but also Vienna Symphonic Library, specifically Special Editions 1 ~ 3.
Still on the lookout for the full set of XD instruments, but as the pictures above state, Edirol Orchestra is used and Kontakt Factory Library along with Stylus and Omnisphere by Spectratronics. Halion's synths were also used with recycled Colosseum instruments.
EDIT: Dammit, I knew Rayquaza's theme used "Find the Exit", I just didn't know it was playing at a snail's pace :P
