I am aware but still. I'm not against toyless but there would go 6 years of collecting.
I doubt Activision cares about collectors in specific, and unlike the situation with Game Freak (Or, rather, The Pokémon Company as a whole) I don't blame them for not caring.
It'd cost way too much to produce figures again, especially to the extent that some people expect them to. Plus, Toys to Life died for a reason, as it just isn't marketable or financially viable anymore.
In addition to that, if they were to reintroduce the core Skylanders games (Which I don't see happening for at least a decade, if at all), they'd likely want to reinvent/reboot it so as to start from a clean slate and make it more accessible to a wider audience.
