I bring this up because earlier this month the PS Blog specifically stated that the RE4 discount would be active for 2 weeks, but earlier this week the blog stated it was only 1 week (and made no mention of the change). I just wanted to inform those whom didn't realize this, or were planning to buy RE4 & RE:CVX at the same time.
My guess is that the last chance page is only updated once a week along everything in the PSN store, being that RE4 is also a new game, it wasn't put there.
This blog post specifically mentions that the RE4 discount is for one week only:
This earlier post mentions it is for two weeks:
I thought it is better to be safe than sorry, if anyone wants to buy this at a discount...
I'm glad it turns out that RE4 is still up for another week at 50% off, but given that the same blog poster made both posts I linked before, this shouldn't have happened at all.
