I think it's likely fake. If you browse Singapore Comic Con website you will find two exhibitors that are Lego related: LEGO Community The Brick Shop Also a little less telling is that it appears that no one from Lego is a guest speaker based on their background image.

I saw the 75243 Slave I, 75259 Snowspeeder, 75258 Anakin's Podracer, and 75261 Clone Scout Walker at my local Walmart tonight. I didn't see the 75262 Imperial Dropship though. Here's the kicker: The Snowspeeder was $32 and Anakin's Podracer was $24. I can't 100% confirm because I didn't look carefully in store, but the Clone Scout Walker is also showing up for $24 on brickseek.com. The Slave I is the normal price. So if you want the Snowspeeder, Anakin's Podracer, or Clone Scout Walker it is probably worthwhile looking them up on brickseek to see if they are in stock and 20% off at your local Walmart. I also searched a couple of other cities (Cincinnati, OH and Indianapolis, IN) in addition to my city (Louisville, KY) and they are also showing up with the discounted prices. However, most stores are showing out of stock so I'd check on brickseek before heading to Walmart.
