It's a two-way road, this video game business. Developers want you to buy their products so, in turn, if you request something from them then you had better be willing to front the cash. During a presentation and Q&A at last night's Warhawk tournament at 3Rooms, Tameem Antoniades (co-founder of Ninja Theory) was asked what his response was to the criticism that Heavenly Sword was too short. He replied that Ninja Theory are definitely interested in extending the experience via downloadable content - but only if it sells well.
The game has been getting good reviews pretty much across the board, with the most common criticism being that there simply isn't enough game to play. With the marketing push that is happening in Europe (we couldn't get through the paper this morning without being greeted by Nariko's face at least twice) we expect the game to sell well, but will it sell enough to persuade Ninja Theory to release extra content? We sincerely hope so. If you want to see it happen, then put down the money and buy the game.
