Should he age? There's no need for him too I suppose. Do I want him to age? Yes, i've been wanting that for a while. I just think it would open up the storyline so much. They could pretty much reinvent him if they wanted too. Ash being an eternal kid is beyond a joke now, of course younger viewers wont feel thay way because they wont have kept up with the show for 10+ years and mostly because they're kids themselves.
