1. who cares if an expansion pack sells more
2. its no mystery if it sells better considering the halo following. its expected to sell more than a single rival release. i would expect gears3 to do the same.
3 very rarely have ps2 games even sold as well as halo or gears on the 360 and thats with over 100mil consoles sold.
4. as a gamer, i rather have 4 quality titles this xmas than 1 xpansion pack.
the point is, as gamers, as long as a game profits and we keep getting quality games, why should we argue? after all, everyone is getting what they want. you should only cry about it if you made an investment or own shares.
its the same story:
sony bots= list of exclusives and quality
xbots= sales figures.
if you really want to talk sales figures, then dont compete against 3rd place, compete against 1st. so, what will ms counter wii sports resort, wii fit with? after all, you aim for no1 not 3!
