So...uh...these 2 keiki have...offshoots? Rootlets?


And these 2 have just grown, may have signs of letting out the same...

Since these are baby plants, you can treat them like that.

If you do not want them, just snip them off of the Dendrobium cane.
If you want to grow them as baby plants, wait until they have several roots 2-3" long. Then if you take a butter knife and wedge it between the cane and the baby plant and apply a little pressure, they will pop right off.
You will need to pot them up in small pots. Some of us here in the States give them away to friends in order to spread baby orchids around. If we give things away like this we often get things in return from these people. We end up trading orchids this way.

What about the older denrobium pseudobulbs/canes?
What will happen to them?

They will continue to provide and perform their main function. That main function is to serve as storage vessels, to store extra water and food reserves.
Occasionally one or more of these typically leafless canes will produce a new growth or a bloom spike. But because of their "storage" function, we should never remove them.

Ok.
Im going to guess that i will be a while before i see another one bloom on account of them being roided and forced to bloom the way wholesale plants usually are(seen this with plenty of cacti)..

You can't really force an orchid to bloom. They are not tulips or paper white Narcissus.

They are wholesaled though. For example: a few hundred thousand Phalaenopsis orchids are wholesaled to the United States to large vendors here. It could even be millions. Often they are shipped in very low bud.
Nobile Dendrobiums are sold by the hundreds from Hawaii to vendors in the States. They probably number in the hundreds of thousands.
But if these orchids are shipped in bud and you buy it in flower, that reblooming of that plant is entirely depended upon the care by you. Phalaenopsis are easy to rebloom but other orchids have varying degrees of difficulty.
Most people feel that the way you get a nobile type Dendrobium to rebloom is by growing them with abundant water and fertilizer. Then when the growth is mature you give it cooler night time temperature and withhold water to some degree.
