I ask this question without any sense of angst, but out of curiosity, as to how it works, and what the cycles are in SL. I have been in various one-on-one and group conversations about this issue, and I find a lot of rumours and speculation about it.
I find that if you put a pricetag on a piece of land, it sells. Funny thing, that. It sells maybe not as quickly as you like, maybe not always as high a price as you like, but it sells, sometimes even in the laggiest, craggiest places. And it sells even if the Lindens roll out 10 new better sims than that, because there's always a reason for somebody to buy that particular parcel.
The question is, will the new continent means that everybody stampedes out there the way they now tend to stampede out to new sims?
I see this happen a lot -- people rush in to settle a new sim where they think it is pretty and not-laggy. They set about actually making it ugly and laggy themselves, but human nature being what it is, they think lag is always something that begins next door, never in my back yard, and then they leave -- taking their lag with them. But...it's human nature, and to be expected. A few remain behind, snap up the cheaper land, and sometimes live happily ever after on a quieter, less laggy sim LOL.
I'm figuring that if the new continent has sand (and what IS a continent anyway? One big chunk? 8 sims? zoned?) or some texture never known to simkind, it will be a huge draw and maybe even get expensive on the auctions. I'm assuming it will be on auctions, but who knows?
Having no experience to compare it to, I'm figuring it will be like Dragon's Cove in TSO (yeah, yeah, go back to TSO where you came from Prokofy, feh). Everyone abandoned Alphaville and the other cities and stampeded into DC and you couldn't even log into it for a time. Then they worked it in a frenzy, then realized even with all the new features it was really same-old, same-old, then they ebbed back to their old places. In SL, with the complexifying factor of land sales and so on, I'm thinking when people surge out, land values will drop farther on the old continent -- in some ways they are already dropping on some mature and most PG -- and then some people will realize they don't have to fight the crowds and lag on the new continent (yes, our old friend Sir Lagalot will be sure to greet us even in this new world). They'll realize that they could go back to the old continent, and pick up some parcels for a song. Then everyone realizing that will drive the prices back up? I dunno.
Most players who have been around compare the continents thing to the snow sims. They figure there will be a huge run on them, an overvaluation, a corrective, an undervaluation, whatever.
Many people, possibly including the Lindens, will be only too happy if the land barons take it in the chops on the new continent. They'll be happy to see their stock devalued. But then they have to balance that against the harsh fact that their own land, and its resale value to be able to move to that new continent, will *also* be devalued. They will liquidate in their zeal to get to the Next Big Thing. And the land barons will get lots MORE cheap land, more than they even had! Then they can afford to sit, and dole it out later. Or they sell it cheap, but with GOM/Lindens working more and more to their favor, they keep cashing out for more.
As with most new game things, some class of people will be sure to suffer, and will be sure to howl. Who will it be this time?
