Probably a flop to Microsoft at least in the UK going by how much titanfall bundle stock there is in the UK.
Also a strange title to promote on xbox one when its technically one of the xbox one's weakest games and MIcrosoft are trying to fight the accurate perception that the ps4 is more powerful.
I think there is geniune desire to see a proper full Titanfall game with both online and offline gameplay. I think Titanfall 2 could be huge.
I'm not planning to buy xbone yet but even if I did I would avoid this bundle. I never subscribe to xbox live and never have. So personally I think its done very well considering many will not be able to actually play this game.
I think in the next few months we will see huge drops in the price of Titanfall in the UK for retail copies. If Microsoft have over-estimated the impact of the game for its bundle so have manufactured too many bundles they may have done the same with the game itself with EA making too many retail copies.
