Microsoft thinks gamers will be too busy playing Rockstar's latest to be concerned with a new title on LIVE Arcade.

Gamerscore Blog's John Porcaro has revealed that there will be no new games released on Xbox LIVE Arcade this week, citing GTA 4 hysteria as the reason.

"There will be no new Xbox LIVE Arcade title this week, and we anticipate all Xbox 360 controllers will be busy with [GTA 4]. We'll be playing as soon as we get our hands on the game, hopefully very, very soon," explained Porcaro.

We're certainly spending a lot of time playing GTA 4 in preparation for a full report on the game's multiplayer offering later this week. In the meantime you can read Tom's 10/10 GTA 4 single-player review.
