This was posted on Polygon like last week. The sale is on the bottom right of the picture and says "all PS Vita game systems" are $200 which means the bundles will be on sale also and with The Walking Dead PS Vita bundle coming out the 20th, maybe you can get that for $200.
This is pretty much the perfect price for the Vita especially if you have PS+. I would recommend you grab the 16 GB memory card and if you don't have PS+, grab a year and you'll be set. If you want any game recommendations, just ask. The Vita is a perfect handheld and with Gamescom set to be a Vita focused show, now's a great time to jump in if you've been on the fence.
