Madden 25 ps3 to ps4 upgrade

I bought the Madden 25 Anniversary edition from Amazon for the sunday ticket promotion and now I want Madden 25 on PS4. Anyone know what the best (i.e. cheapest) way to make my ps3 copy turn into a ps4 copy would be?

Any help is appreciated.

Thanks!

You already missed it... the only upgrade for PS4 that EA promoted was Best Buys where you could trade it in for $45 guaranteed until OCT 4th... I did it on the 4th and now only have to pay $15 for the upgrade.

Best Buy Canada - $45 in-store credit when you trade in the current-gen version of Madden NFL 25. Offer expires seven days after PS4 release. (Canada offer only) - See retailer page for full details.

Future Shop - Trade-in your current-gen version of the game for a $60 credit towards Madden NFL 25 on PS4. Offer expires seven days after PS4 release. (Canada offer only) - See retailer page for full details.

Looks like they took it off since it expired... now only Canadians can get the deal... I think your out of luck.

I have the same issue myself... I don't have a Best Buy anywhere near my area, so that deal wouldn't have applied to me. I want the new version... but only thing I can think of is selling my copy on eBay and using that money towards the new version.
