Okay, unstoppablekem, I voted "wait", but not for the reasons everyone else is. As far as the L1520:
I find it laughable- HILAROUS- that we still have those who think it's specs will be "outdated" anytime soon. Accepting some Earth-shattering, amazing, state of the art jump ahead, I can think of nothing rumored for WP 8.1 that would not run on the L1520. It is an amazing hardware jump up in the world of WP, and I see no reason for anyone who is tempted by this beast to wait. WP 8.1 devices will be "new", and there may be hardware upgrades (though I truly doubt it myself), but light years ahead enough to make Kin Kong Bundy here obsolete?? (See what I did there?) No way. Not a chance.
HOWEVER....
There is something about waiting for the right thing. I love the L1520, but at the price it is at, that 6" screen drawback has kept me away. For some, it is just the price. For some, it is some other small ditty that they just can't put their finger on. For you, just the fact you dropped this poll tells me you should wait. It is only a matter of months, your phone still rocks, and there is no hurry.
I am not sure what will be announced at WMC. But, we may get a surprise or 2. And within 2 months, you could be comparing some fun new toys.
Let's say WP 8.1 is announced in April, and devices hit in May. If you can put yourself on a tight leash and hold out that long, there will be some great new stuff. I am sure the rumored Samsung will come out then, and surely Nokia and HTC won't be sitting on the sideline. Fun, fun, fun!!
BUT...
If not, there will still be shiney, new, 6" of awesome L1520's waiting to be taken home and loved. The price may even drop. I am sure they will get WP 8.1 upgrades, and you are out nothing as you and your current phone will have more memories to be shared.
Oh, it will still NOT be outdated.
"Kin" Kong Bundy.... GET IT???
I crack myself up.....
