NVIDIA's next generation Ion platform was announced back in early March, so naturally we've been wondering where all the souped-up netbooks based on the tech have been hiding. We wish we had better news, but it looks like the wait will have to go on a little while longer. While NVIDIA claims no delay on its end, ASUS and Acer have confirmed that their respective Ion 2 netbooks will not arrive until the end of May or even as late as the beginning of June in the US. The 12-inch ASUS 1201PN, which packs a dual-core Atom processor and a 16-core Ion chip, is set to hit Europe and Asia in mid to late May and will make its US debut in June. Similarly, Acer's 10-inch Aspire One 532G is planned to be released around Computex in early June. We just have a feeling there will be some more joining the Ion 2 netbook brigade in the interim, but it's looking like we'll just have to kick off the summer with another Ion showdown.
