Help me understand pre-sales at the Broadhurst (Anastasia)

I'm looking at tickets for Anastasia on Telecharge. From what I can tell, they're doing pre-sales now for American Express card holders through tomorrow morning (I think Audience Reward members have access right at 10am tomorrow); regular sales start in Oct.

As an AmEx holder looking for just regular tickets (not the super duper pricier AmEx tickets), I'm only seeing a very small number available on each date. If I wait until tomorrow for Audience Rewards access, or even regular sales, will more tickets be available? I guess what I'm very inarticulately trying to say is I don't understand why it seems like only 15-20 tickets are available now through the AmEx presales- is that typical offerings for pre-sales, and if so, am I better off waiting till the regular sales to get a better range of options? Or have that many people already bought tickets and that's just what's left?

Also, I can get Row B (Left Orchestra) seats 1-3, so right on the aisle. Do you think that would be too close or too off-center?

Thanks!

When I checked, i saw a vast amount of tickets in the side/rear orchestra and a ton in the mezzanine.

I assume center Orch will be released for public on-sale.
