I'd like to add that one rationale that was discussed during other UCM poll threads was whether or not these toys would be considered to be meaningful Transformer action figures in their own right. The basic way to answer this question is to ask yourself, "Would I buy this toy if it were sold on its own?" (and you didn't necessarily intend on buying another Transformer to interact with it)
I've come across a similar 'general rule', relating to how it is reviewed - would you review it on its own or with another figure. Generally*, if smaller figures in a multi-pack is rarely seen reviewed on its own, most would often not count it as a stand-alone toy when counting a collection. Example, would you see reviews of any of the following on their own - AM partners, Scamper, individual components of either ROTF Devastator, Nebulans?
Just because PCC's partners are called the same as Armada TFs partners, doesn't mean they have to be lumped together. This is a new line with a new concept/gimmick that differs from Armada Minicons. We are only getting 9 PCC 2-packs (9 Minicons) this year (according to Hasbro), so until we start getting more of a story and characterisation behind these Minicons, I won't be deciding until later.

(* 'Generally' doesn't mean 'always', so it can still be messy with exceptions occuring)
