I'll be the first to admit that I could be completely off-base here. I used Linux (as opposed to other, for-pay OSes) to sort-of illustrate - probably not really well - where most Antonia users are about their figure vs other figures. Linux users in general - and the whole Linux mindset - doesn't care about market penetration. If you'd read that article I posted a link to, that would have been clear.

Antonia represents choice. Now, users have had choice before - Miki3 / Mariko / other for-pay figures - but what Antonia re-surfacing as a finished, standardised figure was meant to represent was that Poser users didn't need to wait for a content creator who was focused on making the next version of a series of figures they'd come to depend as an application-specific figure (i.e., requires DS4 to work properly), to condescend to make a version of this figure for their programme of choice. Antonia works brilliantly well in Poser as is. And the weight-mapped version showcases Poser's weightmapping system brilliantly well.

That's it.

Whether Antonia becomes the next V4 in terms of popularity is completely immaterial. She has already achieved her goal: she was the first figure to highlight was the newest version Poser can do (Dregon aside - haven't really heard much about that one, anyway).
Figure creators have been inspired and new figures are on the horizon because Antonia has shown that the potential of viability of a non-Millenium series figure is significantly more assured than it has been in the past, naysayers notwithstanding.

What is significant is that the focus in no longer on a figure or a series of figures: it's on the programme and associated technology. DS4 and Genesis offer a complete solution ... and Poser 9 / PP2012 are doing the same as new figures (and re-rigged, weightmapped older figures) take advantage of the technology offered by this programme.
