The PS3 is still hard to develop for. What's changed is that they've finally shipped enough units to make ports worthwhile.<p>The 360 has three symmetric cores and a decent GPU. The PS3 has a single core, a comparable GPU - and six very constrained SPUs that you'd better learn to juggle if you want your PS3 game to even approximate the quality of a 360 title. There are more than a few games that crippled their 360 version to match what they could achieve on the PS3.<p>To be fair, the PS3 <i>is</i> easier to develop for than the PS2 and it <i>has</i> gotten easier over time, but if you take the 360 as the benchmark the PS3 will always be hard in comparison.
