Ok here's some dethi rummiations
Since b/w doesn't have color info, you could "fit" 50% more time in b/w with the same compression quality on a DVD disc.
So a single layer disc could fit 90minutes of b/w with the minimum mpeg2 compression, and a double layer disc 3 hours..
Treasure 2-disc sets have an average (I think) of about 4 hours in color since they usually use near minimum compression. B/w Treasures could last 6 hours without sacrificing quality.
(Some DVD titles on the other hand, use much more compression than minimum, for example, when you have 2 versions (pan-scan/widescreen) of a 2 hour color movie on a double layer disc you're actually compressing it twice more than the minimum.)
Mickey in B/W 2:
I count 40 missing mickey b/w shorts (7 with Pete!). At 7-8 minutes each, that's between 4 hours 40 minutes to 5 hours 20 minutes for all of them.. They all could fit easily into a two disc set using the best quality, minimum compression. No reason or justification there for not including them all on this treasure.
Pluto:
With 48 Pluto shorts in color, if you wanted to use minimum compression, you could only fit around 30-35 on 2 discs, with no extras. So maybe that's why they may justify they being splitted. (Of course you could fit all the remaining ones on just one 2-disc set with more compression)
Or they could do it as a 3 disc set which would make it very special. But I don't think that's gonna happen.
Mickey Mouse Club:
If the 66 MMC shows lasted about 50-55 minutes, and they were in b/w, you would need about 18 to 20 double layer discs for 66 "hour" episodes at the minimum compression with no extras.
Since 2099net said they switched to half hour shows at some point, this figure would be less.
On a 2 disc treasure they can only fit 6 to 7 "hour" b/w ones that way, so the week's worth (5) with extras seems appropiate.
If they are in color you would need 28 to 30 discs for 66 episodes. A 2 disc treasure could fit the week's 5 in color with a little more (like 10% more) than minimum compression with no extras. With extras they would need to increase compresion like an additional 25% more for an hour of supplementary material, 50% more for 2 hours, etc etc. (Or they could compress the extra material to hell
)
Further thoughts on Mickey B/W releases:

And since the Laserdisc was NTSC, that might explain why there's no PAL release of this, while it was released in Japan (NTSC). No PAL masters being created at the Laserdisc time, nor new transfers done just solely for PAL at the DVD's release.
Which would mean, that there might not be a PAL b/w volume 2 offered, unless they now decided to do new transfers for the first b/w batch for the PAL market. (or they could done PAL transfers for volume 2 and offer this as a stand alone PAL volume X
which would be weird if it had no Steamboat Willie. (Didn't there was a momentary period in which the UK press release for MM in living color seemed to give the impression there would be some b/w included? maybe this is related.)

And I still think Chrono Donald 2 shoulda been included with this wave
