@Mr_Cynical, This is for the PC version of TF2. Please do not upbid this article as it posted in the completely wrong place and has nothing to do with the title it was posted under.
The upcoming Pyro update bound for Valve's multiplayer shooter Team Fortress 2 is "almost completely wrapped" and will include changes to the core class beyond the addition of unlockable weapons and achievements, the company revealed in a Steam client update today.
I meant that Portal 2 / Episode 3 will probably use a revision of the Source Engine. Valve have added significant features to each Episode released so far so it won't be case of pop in the Orange Box disc and play Ep3 or Portal 2.
To offer them as DLC they'll need the engine as well which makes the file sizes much bigger. Maybe by then MS will be open to much bigger games being offered for download. They do Shivering Isles, map packs & Xbox Originals like you say.
i dont know what you mean by "wonders". The size limit only applies to Xbox Live Arcade games. It does not apply to game addons/expansions or even demos.
GamesIndustry.biz has learnt that Valve asked Microsoft if it was possible to place its award-winning Orange Box title, Portal, on Xbox Live Arcade for download, but that it was rejected.
