It is regrettable if AP has to miss the holiday sales season, but I take a Blizzard view of delays: the game should release when it's ready and not a moment before. I especially appreciate this because Obsidian has been screwed before in having to push an unfinished game out the door to make a seasonal deadline (KOTOR2).
But...
Releasing the game in June is a horrible, horrible, horrible idea. A June release is the game equivalent of having your television show placed on a Friday night lineup. June is a transition time, with all the transitions working against you.
- Kids are leaving college, and are looking to get *rid* of stuff, not pick stuff up.
- Most people are transitioning out of the academic year and into the summer, and especially for familys with young kids, a lot of income goes to camps, day care, essentials. Not games.
- Good weather means less time indoors, less inclination to want to start a game, much less a (presumably) fairly lengthy RPG.
- Summer movies and summer concerts have all the entertainment hype, not summer games.
A better time, if you are shooting for that time period, would be mid/late-August/early September. A lot of those same transitiions are in reverse, and this time working for you. The sports game hype (Madden mainly) combined with thinking about school/fall gets people back into a video game mood. There's a reason why Square owned this period for a number of years back in the PSX/PS2 days. Much like Arkham Asylum did this past August, you can own that period as the big "non-sports" title for people to think about while at the same time using that Madden hype to draw attention to yourself.
Just not June, please.
