It feels like they are burning away their competitive LCGs. We only have two left (AGOT and L5R). So far all the new competitive card games they've announced have been blind purchase. I've long suspected that they are rethinking the idea of a viable long term competitive LCG. There are many downsides to the model as far as sustainability is concerned. I hope if they announce a new competitive LCG they look hard at their model and try to address things like barrier of entry and more rapidly correcting toxic card pools. The co-ops (because of their nature) don't have this issue so the model as implemented today works just fine for LOTR and AH:TCG.
My guess would be if they announce another card game any time soon it would be Android themed considering they have a huge library of art for that world, but no active card game to put those assets to work. Though I also sincerely wonder if they'll release another competitive LCG or if they just go co-op with the LCG model going forward since that just seems like an easier fit.
