The real $50 difference in savings is 3G. YMMV i'd say. For most, that is not worth even close to $50, which is why the 3G isn't selling.
Exactly. No one was buying the 3G bundle at full price. However, before these BF deals started people were actually buying the AC3 bundle at MSRP because it was the best deal available.
No, sorry guys but it really isn't a better value. If you were to buy the Vita bundle at full price ($250 for Vita, AC3, and 4 gig stick), three months of Plus ($18), and All-Stars ($40) you'd be paying $308. You paid $180, a savings of $128.
With this bundle you are getting a 3G Vita ($300 and 8 gig stick), two games (up to $40 each depending on what you choose) for a total cost of $380. You pay $199, a savings of $181.
Yes Uncharted and Wipeout are free with PS Plus, but that's only as long as you maintain a paid subscription ($50 a year at the cheapest), and there's no guarantee that those games will remain available forever (which they haven't in the past).
The problem with that is.. if you're basing it on the MSRP values for each bundle, the AC3 bundle is a better deal to begin with. Hardly anyone is going to use 3G, and many will be upgrading the 8gb card. 8gb is enough if you're ok with keeping just a few games on the card, and swapping them out whenever you need to.. but you'll probably be upgrading if you buy a lot of stuff off of PSN.
Yes, you won't keep the free PS+ games permanently if you don't keep your subscription, but TBH 3 months of PS+ is more than enough time to finish or play through Uncharted and Wipeout extensively. Not only that, but many CAGs got a crap ton of free PS+ codes from IGN recently. The game choices from the 3G Vita bundle don't seem so great, the best choice if you already have PS+ is probably Hot Shots Golf which is consistently cheap..
