The land prices have been going down, down, down over the last few months. Anyone who's got a free parcel, either it is free for rent or sale, has quite some problems to find a new owner for it.
Also big players like Dreamland have lowered their prices to get new tenants or sell it. In addition the in world sales of virtual goods are not as quite good at the moment as they used to be, many people in this field are complaining about the lack of sales.
So how does it come? Well, the big hype over SL is over in most countries at the moment, it's not so unusual anymore, now SL needs to show its value as a tool for whichever need. But end of the hype means also that the stream of newbies flowing into SL has ebbed down great scale.
So what's next? I guess many landlords are forced to either sell their land now under value and/or just give up many islands. That's what I expect at least. Not everyone has enough bucks in the background to overcome this time now.
I don't expect Lindenlab to lower their own prices, though.
