At least you couched the statement by using the "IMO" moniker. However, to imply that this ammo will be obsolete "soon" is simply not based in fact...(or perhaps it is and Iam wrong, in which case you could giveme some factsproving you are right)

For example, when was the last time a comparable number of firearms was produced in a single caliber in such a short time, and how long was it before ammo was no longer commercialy produced for it? Secondly, what is the average time span between the cessation of acommerciallyproduced firearm in a specific caliber, and the cessation of the production of the corresponding ammo.

If you can answer some of these questions on a factual basis then I could presume that your opinion is based on industry data and in a commercially significant basis.
