So we agree, it's not a few pages. Unless the definition of "few" has drastically changed.
The options on the pregens are already there. Add a couple of spells, a couple of options, and a page about choosing between them.
Elf is probably there, dwarf is probably there, hobbit <del><del> halfling is probably there and human. Fighter, thief, wizard, and cleric are probably already there, up to 5th level. equipment is probably already there, and maybe even options to buy different equipment.
And I don't think anyone is talking about taking away the content that is already there. It's already a quick play box, just add chargen.
Even WotC agrees that chargen is important for the starter set, enough to make 15% of the PHB free on line. In my ideal the package would say, 'If you want more, here is some chargen rules right here in the box, and even more on line'. It's already a loss leader, and it looks like it doesn't contain the poster map and counters of the 4e starter. Are the page counts the same?
But it is a moot point. It won't change, it is what it is. Besides I don't think 5e's success hinges on this starter.
I do think it'd be a better product and really hook gamers that don't yet know they are gamers. I think chargen is very important for that. Not everyone is a rpg gamer.
