Thanks for the reply kblood. I'm really upset to hear this news and sadly hooking my computer up to the internet temporarily isn't an option as my computer doesn't have a modem (silly I know but I had to save money on my new system somehow).
I guess my next question is, if I wait until TOMI's season is complete and order the DVD boxset from TellTale, will I able to play offline? This was the case with seasons' 1 & 2 of Sam and Max. I really hope TellTale does the same for Monkey Island because this seems like a fair trade off for those without Internet connections at least.
I suppose the only other possibility would be to download a cracked version of the game and then pay TellTale (even though I wouldn't actually be downloading the games from them). I can't be alone in thinking that this would just prove that DRM is a waste of time?!
